wireprotov2: remove "compression" from capabilities response

This is not used. And future commits will change how this mechanism
works. Let's remove it.

As a bonus, this fixes some test failures on pure installs (due to
zstd references).

 **Experimental and under active development**
 
 This section documents the wire protocol commands exposed to transports
 using the frame-based protocol. The set of commands exposed through
 these transports is distinct from the set of commands exposed to legacy
 transports.
 
 The frame-based protocol uses CBOR to encode command execution requests.
 All command arguments must be mapped to a specific or set of CBOR data
 types.
 
 The response to many commands is also CBOR. There is no common response
 format: each command defines its own response format.
 
 TODOs
 =====
 
 * Add "node namespace" support to each command. In order to support
   SHA-1 hash transition, we want servers to be able to expose different
   "node namespaces" for the same data. Every command operating on nodes
   should specify which "node namespace" it is operating on and responses
   should encode the "node namespace" accordingly.
 
 Commands
 ========
 
 The sections below detail all commands available to wire protocol version
 2.
 
 branchmap
 ---------
 
 Obtain heads in named branches.
 
 Receives no arguments.
 
 The response is a map with bytestring keys defining the branch name.
 Values are arrays of bytestring defining raw changeset nodes.
 
 capabilities
 ------------
 
 Obtain the server's capabilities.
 
 Receives no arguments.
 
 This command is typically called only as part of the handshake during
 initial connection establishment.
 
 The response is a map with bytestring keys defining server information.
 
 The defined keys are:
 
 commands
    A map defining available wire protocol commands on this server.
 
    Keys in the map are the names of commands that can be invoked. Values
    are maps defining information about that command. The bytestring keys
    are:
 
       args
          (map) Describes arguments accepted by the command.
 
          Keys are bytestrings denoting the argument name.
 
          Values are maps describing the argument. The map has the following
          bytestring keys:
 
          default
             (varied) The default value for this argument if not specified. Only
             present if ``required`` is not true.
 
          required
             (boolean) Whether the argument must be specified. Failure to send
             required arguments will result in an error executing the command.
 
          type
             (bytestring) The type of the argument. e.g. ``bytes`` or ``bool``.
 
          validvalues
             (set) Values that are recognized for this argument. Some arguments
             only allow a fixed set of values to be specified. These arguments
             may advertise that set in this key. If this set is advertised and
             a value not in this set is specified, the command should result
             in error.
 
       permissions
          An array of permissions required to execute this command.
 
-compression
-   An array of maps defining available compression format support.
-
-   The array is sorted from most preferred to least preferred.
-
-   Each entry has the following bytestring keys:
-
-      name
-         Name of the compression engine. e.g. ``zstd`` or ``zlib``.
-
 framingmediatypes
    An array of bytestrings defining the supported framing protocol
    media types. Servers will not accept media types not in this list.
 
 pathfilterprefixes
    (set of bytestring) Matcher prefixes that are recognized when performing
    path filtering. Specifying a path filter whose type/prefix does not
    match one in this set will likely be rejected by the server.
 
 rawrepoformats
    An array of storage formats the repository is using. This set of
    requirements can be used to determine whether a client can read a
    *raw* copy of file data available.
 
 redirect
    A map declaring potential *content redirects* that may be used by this
    server. Contains the following bytestring keys:
 
    targets
       (array of maps) Potential redirect targets. Values are maps describing
       this target in more detail. Each map has the following bytestring keys:
 
       name
          (bytestring) Identifier for this target. The identifier will be used
          by clients to uniquely identify this target.
 
       protocol
          (bytestring) High-level network protocol. Values can be
          ``http``, ```https``, ``ssh``, etc.
 
       uris
           (array of bytestrings) Representative URIs for this target.
 
       snirequired (optional)
           (boolean) Indicates whether Server Name Indication is required
           to use this target. Defaults to False.
 
       tlsversions (optional)
           (array of bytestring) Indicates which TLS versions are supported by
           this target. Values are ``1.1``, ``1.2``, ``1.3``, etc.
 
    hashes
       (array of bytestring) Indicates support for hashing algorithms that are
       used to ensure content integrity. Values include ``sha1``, ``sha256``,
       etc.
 
 changesetdata
 -------------
 
 Obtain various data related to changesets.
 
 The command accepts the following arguments:
 
 noderange
    (array of arrays of bytestrings) An array of 2 elements, each being an
    array of node bytestrings. The first array denotes the changelog revisions
    that are already known to the client. The second array denotes the changelog
    revision DAG heads to fetch. The argument essentially defines a DAG range
    bounded by root and head nodes to fetch.
 
    The roots array may be empty. The heads array must be defined.
 
 nodes
    (array of bytestrings) Changelog revisions to request explicitly.
 
 nodesdepth
    (unsigned integer) Number of ancestor revisions of elements in ``nodes``
    to also fetch. When defined, for each element in ``nodes``, DAG ancestors
    will be walked until at most N total revisions are emitted.
 
 fields
    (set of bytestring) Which data associated with changelog revisions to
    fetch. The following values are recognized:
 
    bookmarks
       Bookmarks associated with a revision.
 
    parents
       Parent revisions.
 
    phase
       The phase state of a revision.
 
    revision
       The raw, revision data for the changelog entry. The hash of this data
       will match the revision's node value.
 
 The server resolves the set of revisions relevant to the request by taking
 the union of the ``noderange`` and ``nodes`` arguments. At least one of these
 arguments must be defined.
 
 The response bytestream starts with a CBOR map describing the data that follows.
 This map has the following bytestring keys:
 
 totalitems
    (unsigned integer) Total number of changelog revisions whose data is being
    transferred. This maps to the set of revisions in the requested node
    range, not the total number of records that follow (see below for why).
 
 Following the map header is a series of 0 or more CBOR values. If values
 are present, the first value will always be a map describing a single changeset
 revision.
 
 If the ``fieldsfollowing`` key is present, the map will immediately be followed
 by N CBOR bytestring values, where N is the number of elements in
 ``fieldsfollowing``. Each bytestring value corresponds to a field denoted
 by ``fieldsfollowing``.
 
 Following the optional bytestring field values is the next revision descriptor
 map, or end of stream.
 
 Each revision descriptor map has the following bytestring keys:
 
 node
    (bytestring) The node value for this revision. This is the SHA-1 hash of
    the raw revision data.
 
 bookmarks (optional)
    (array of bytestrings) Bookmarks attached to this revision. Only present
    if ``bookmarks`` data is being requested and the revision has bookmarks
    attached.
 
 fieldsfollowing (optional)
    (array of 2-array) Denotes what fields immediately follow this map. Each
    value is an array with 2 elements: the bytestring field name and an unsigned
    integer describing the length of the data, in bytes.
 
    If this key isn't present, no special fields will follow this map.
 
    The following fields may be present:
 
    revision
       Raw, revision data for the changelog entry. Contains a serialized form
       of the changeset data, including the author, date, commit message, set
       of changed files, manifest node, and other metadata.
 
       Only present if the ``revision`` field was requested.
 
 parents (optional)
    (array of bytestrings) The nodes representing the parent revisions of this
    revision. Only present if ``parents`` data is being requested.
 
 phase (optional)
    (bytestring) The phase that a revision is in. Recognized values are
    ``secret``, ``draft``, and ``public``. Only present if ``phase`` data
    is being requested.
 
 If nodes are requested via ``noderange``, they will be emitted in DAG order,
 parents always before children.
 
 If nodes are requested via ``nodes``, they will be emitted in requested order.
 
 Nodes from ``nodes`` are emitted before nodes from ``noderange``.
 
 The set of changeset revisions emitted may not match the exact set of
 changesets requested. Furthermore, the set of keys present on each
 map may vary. This is to facilitate emitting changeset updates as well
 as new revisions.
 
 For example, if the request wants ``phase`` and ``revision`` data,
 the response may contain entries for each changeset in the common nodes
 set with the ``phase`` key and without the ``revision`` key in order
 to reflect a phase-only update.
 
 TODO support different revision selection mechanisms (e.g. non-public, specific
 revisions)
 TODO support different hash "namespaces" for revisions (e.g. sha-1 versus other)
 TODO support emitting obsolescence data
 TODO support filtering based on relevant paths (narrow clone)
 TODO support hgtagsfnodes cache / tags data
 TODO support branch heads cache
 TODO consider unify query mechanism. e.g. as an array of "query descriptors"
 rather than a set of top-level arguments that have semantics when combined.
 
 filedata
 --------
 
 Obtain various data related to an individual tracked file.
 
 The command accepts the following arguments:
 
 fields
    (set of bytestring) Which data associated with a file to fetch.
    The following values are recognized:
 
    parents
       Parent nodes for the revision.
 
    revision
       The raw revision data for a file.
 
 haveparents
    (bool) Whether the client has the parent revisions of all requested
    nodes. If set, the server may emit revision data as deltas against
    any parent revision. If not set, the server MUST only emit deltas for
    revisions previously emitted by this command.
 
    False is assumed in the absence of any value.
 
 nodes
    (array of bytestrings) File nodes whose data to retrieve.
 
 path
    (bytestring) Path of the tracked file whose data to retrieve.
 
 TODO allow specifying revisions via alternate means (such as from
 changeset revisions or ranges)
 
 The response bytestream starts with a CBOR map describing the data that
 follows. It has the following bytestream keys:
 
 totalitems
    (unsigned integer) Total number of file revisions whose data is
    being returned.
 
 Following the map header is a series of 0 or more CBOR values. If values
 are present, the first value will always be a map describing a single changeset
 revision.
 
 If the ``fieldsfollowing`` key is present, the map will immediately be followed
 by N CBOR bytestring values, where N is the number of elements in
 ``fieldsfollowing``. Each bytestring value corresponds to a field denoted
 by ``fieldsfollowing``.
 
 Following the optional bytestring field values is the next revision descriptor
 map, or end of stream.
 
 Each revision descriptor map has the following bytestring keys:
 
 Each map has the following bytestring keys:
 
 node
    (bytestring) The node of the file revision whose data is represented.
 
 deltabasenode
    (bytestring) Node of the file revision the following delta is against.
 
    Only present if the ``revision`` field is requested and delta data
    follows this map.
 
 fieldsfollowing
    (array of 2-array) Denotes extra bytestring fields that following this map.
    See the documentation for ``changesetdata`` for semantics.
 
    The following named fields may be present:
 
    ``delta``
       The delta data to use to construct the fulltext revision.
 
       Only present if the ``revision`` field is requested and a delta is
       being emitted. The ``deltabasenode`` top-level key will also be
       present if this field is being emitted.
 
    ``revision``
       The fulltext revision data for this manifest. Only present if the
       ``revision`` field is requested and a fulltext revision is being emitted.
 
 parents
    (array of bytestring) The nodes of the parents of this file revision.
 
    Only present if the ``parents`` field is requested.
 
 When ``revision`` data is requested, the server chooses to emit either fulltext
 revision data or a delta. What the server decides can be inferred by looking
 for the presence of the ``delta`` or ``revision`` keys in the
 ``fieldsfollowing`` array.
 
 heads
 -----
 
 Obtain DAG heads in the repository.
 
 The command accepts the following arguments:
 
 publiconly (optional)
    (boolean) If set, operate on the DAG for public phase changesets only.
    Non-public (i.e. draft) phase DAG heads will not be returned.
 
 The response is a CBOR array of bytestrings defining changeset nodes
 of DAG heads. The array can be empty if the repository is empty or no
 changesets satisfied the request.
 
 TODO consider exposing phase of heads in response
 
 known
 -----
 
 Determine whether a series of changeset nodes is known to the server.
 
 The command accepts the following arguments:
 
 nodes
    (array of bytestrings) List of changeset nodes whose presence to
    query.
 
 The response is a bytestring where each byte contains a 0 or 1 for the
 corresponding requested node at the same index.
 
 TODO use a bit array for even more compact response
 
 listkeys
 --------
 
 List values in a specified ``pushkey`` namespace.
 
 The command receives the following arguments:
 
 namespace
    (bytestring) Pushkey namespace to query.
 
 The response is a map with bytestring keys and values.
 
 TODO consider using binary to represent nodes in certain pushkey namespaces.
 
 lookup
 ------
 
 Try to resolve a value to a changeset revision.
 
 Unlike ``known`` which operates on changeset nodes, lookup operates on
 node fragments and other names that a user may use.
 
 The command receives the following arguments:
 
 key
    (bytestring) Value to try to resolve.
 
 On success, returns a bytestring containing the resolved node.
 
 manifestdata
 ------------
 
 Obtain various data related to manifests (which are lists of files in
 a revision).
 
 The command accepts the following arguments:
 
 fields
    (set of bytestring) Which data associated with manifests to fetch.

    revision
       The raw revision data for the manifest.
 
 haveparents
    (bool) Whether the client has the parent revisions of all requested
    nodes. If set, the server may emit revision data as deltas against
    any parent revision. If not set, the server MUST only emit deltas for
    revisions previously emitted by this command.
 
    False is assumed in the absence of any value.
 
 nodes
    (array of bytestring) Manifest nodes whose data to retrieve.
 
 tree
    (bytestring) Path to manifest to retrieve. The empty bytestring represents
    the root manifest. All other values represent directories/trees within
    the repository.
 
 TODO allow specifying revisions via alternate means (such as from changeset
 revisions or ranges)
 TODO consider recursive expansion of manifests (with path filtering for
 narrow use cases)
 
 The response bytestream starts with a CBOR map describing the data that
 follows. It has the following bytestring keys:
 
 totalitems
    (unsigned integer) Total number of manifest revisions whose data is
    being returned.
 
 Following the map header is a series of 0 or more CBOR values. If values
 are present, the first value will always be a map describing a single manifest
 revision.
 
 If the ``fieldsfollowing`` key is present, the map will immediately be followed
 by N CBOR bytestring values, where N is the number of elements in
 ``fieldsfollowing``. Each bytestring value corresponds to a field denoted
 by ``fieldsfollowing``.
 
 Following the optional bytestring field values is the next revision descriptor
 map, or end of stream.
 
 Each revision descriptor map has the following bytestring keys:
 
 node
    (bytestring) The node of the manifest revision whose data is represented.
 
 deltabasenode
    (bytestring) The node that the delta representation of this revision is
    computed against. Only present if the ``revision`` field is requested and
    a delta is being emitted.

       present if this field is being emitted.
 
    ``revision``
       The fulltext revision data for this manifest. Only present if the
       ``revision`` field is requested and a fulltext revision is being emitted.
 
 parents
    (array of bytestring) The nodes of the parents of this manifest revision.
    Only present if the ``parents`` field is requested.
 
 When ``revision`` data is requested, the server chooses to emit either fulltext
 revision data or a delta. What the server decides can be inferred by looking
 for the presence of ``delta`` or ``revision`` in the ``fieldsfollowing`` array.
 
 pushkey
 -------
 
 Set a value using the ``pushkey`` protocol.
 
 The command receives the following arguments:
