extensions: deprecate extsetup without a `ui` argument (API)

9.5 years should be enough time, but there were some tests for the old style
still (which are now updated).  Exthelper doesn't fallback to the old API, so
this is for consistency.

.. api::

   The extension hook ``extsetup`` without a `ui` argument has been deprecated,
   and will be removed in the next version.  Add a `ui` argument to avoid the
   deprecation warning.

 """syntax highlighting for hgweb (requires Pygments)
 
 It depends on the Pygments syntax highlighting library:
 http://pygments.org/
 
 There are the following configuration options::
 
   [web]
   pygments_style = <style> (default: colorful)
   highlightfiles = <fileset> (default: size('<5M'))
   highlightonlymatchfilename = <bool> (default False)
 
 ``highlightonlymatchfilename`` will only highlight files if their type could
 be identified by their filename. When this is not enabled (the default),
 Pygments will try very hard to identify the file type from content and any
 match (even matches with a low confidence score) will be used.

     Wrapping methods of the repository object is not recommended since
     it conflicts with extensions that extend the repository by
     subclassing. All extensions that need to extend methods of
     localrepository should use this subclassing trick: namely,
     reposetup() should look like

           class myrepo(repo.__class__):

                   [...extension stuff...]
 
           repo.__class__ = myrepo
 
     In general, combining wrapfunction() with subclassing does not
     work. Since you cannot control what other extensions are loaded by
     your end users, you should play nicely with others by using the
     subclass trick.

 Test that dirstate changes aren't written out at the end of "hg

 acquisition of wlock in workingctx._poststatusfixup().
 
 This avoidance is important to keep consistency of dirstate in race
 condition (see issue5584 for detail).

 "hg status" below should excludes "e", of which exec flag is set, for
 portability of test scenario, because unsure but missing "e" is
 treated differently in _checklookup() according to runtime platform.
 
 - "missing(!)" on POSIX, "pctx[f].cmp(self[f])" raises ENOENT
 - "modified(M)" on Windows, "self.flags(f) != pctx.flags(f)" is True

 Test that invalidating fsmonitor state in the middle (which doesn't require the
 wlock) causes the fsmonitor update to be skipped.
 hg debugrebuilddirstate ensures that the dirstaterace hook will be called, but
 it also invalidates the fsmonitor state. So back it up and restore it.

 Configure a merge tool that runs status in the middle of the rebase. The goal of
 the status call is to trigger a potential bug if fsmonitor's state is written
 even though the wlock is held by another process. The output of 'hg status' in
 the merge tool goes to /dev/null because we're more interested in the results of
 'hg status' run after the rebase.

 Examine whether module loading is delayed until actual referring, even
 though module is imported with "absolute_import" feature.
 
 Files below in each packages are used for described purpose:
 
 - "called": examine whether "from MODULE import ATTR" works correctly
 - "unused": examine whether loading is delayed correctly
 - "used":   examine whether "from PACKAGE import MODULE" works correctly
 
 Package hierarchy is needed to examine whether demand importing works
 as expected for "from SUB.PACK.AGE import MODULE".

   use external program to diff repository (or selected files)
   
       Show differences between revisions for the specified files, using an
       external program. The default program used is diff, with default options
       "-Npru".
   
       To select a different program, use the -p/--program option. The program
       will be passed the names of two directories to compare. To pass additional
       options to the program, use -o/--option. These will be passed before the
       names of the directories to compare.
   
       When two revision arguments are given, then changes are shown between
       those revisions. If only one revision is specified then that revision is
       compared to the working directory, and, when no revisions are specified,
       the working directory files are compared to its parent.

   $ hg help --extension extdiff
   extdiff extension - command to allow external programs to compare revisions
   
   The extdiff Mercurial extension allows you to use external programs to compare
   revisions, or revision with working directory. The external diff programs are
   called with a configurable set of options and two non-option arguments: paths
   to directories containing snapshots of files to compare.
   
   If there is more than one file being compared and the "child" revision is the
   working directory, any modifications made in the external diff program will be
   copied back to the working directory from the temporary directory.
   
   The extdiff extension also allows you to configure new diff commands, so you
   do not need to type 'hg extdiff -p kdiff3' always.
   
     [extdiff]
     # add new command that runs GNU diff(1) in 'context diff' mode
     cdiff = gdiff -Nprc5
     ## or the old way:
     #cmd.cdiff = gdiff
     #opts.cdiff = -Nprc5
   
     # add new command called meld, runs meld (no need to name twice).  If
     # the meld executable is not available, the meld tool in [merge-tools]
     # will be used, if available
     meld =
   
     # add new command called vimdiff, runs gvimdiff with DirDiff plugin
     # (see http://www.vim.org/scripts/script.php?script_id=102) Non
     # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
     # your .vimrc
     vimdiff = gvim -f "+next" \
               "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
   
   Tool arguments can include variables that are expanded at runtime:
   
     $parent1, $plabel1 - filename, descriptive label of first parent
     $child,   $clabel  - filename, descriptive label of child revision
     $parent2, $plabel2 - filename, descriptive label of second parent
     $root              - repository root
     $parent is an alias for $parent1.
   
   The extdiff extension will look in your [diff-tools] and [merge-tools]
   sections for diff tool arguments, when none are specified in [extdiff].
   
     [extdiff]
     kdiff3 =
   
     [diff-tools]
     kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
   
   You can use -I/-X and list of file or directory names like normal 'hg diff'
   command. The extdiff extension makes snapshots of only needed files, so
   running the external diff program will actually be pretty fast (at least
   faster than having to compare the entire tree).
   
   list of commands:
   
    extdiff       use external program to diff repository (or selected files)

 Disabled extension commands:
 
   $ ORGHGRCPATH=$HGRCPATH
   $ HGRCPATH=

   $ hg help email
   'email' is provided by the following extension:
   
       patchbomb     command to send changesets as (a series of) patch emails
   
   (use 'hg help extensions' for information on enabling extensions)
 
 
   $ hg qdel
   hg: unknown command 'qdel'
   'qdelete' is provided by the following extension:
   
       mq            manage a stack of patches
   
   (use 'hg help extensions' for information on enabling extensions)
   [255]
 
 
   $ hg churn
   hg: unknown command 'churn'
   'churn' is provided by the following extension:
   
       churn         command to display statistics about repository history
   
   (use 'hg help extensions' for information on enabling extensions)
   [255]
 
 
 
 Disabled extensions:
 
   $ hg help churn
   churn extension - command to display statistics about repository history
   
   (use 'hg help extensions' for information on enabling extensions)
 
   $ hg help patchbomb
   patchbomb extension - command to send changesets as (a series of) patch emails
   
   The series is started off with a "[PATCH 0 of N]" introduction, which
   describes the series as a whole.
   
   Each patch email has a Subject line of "[PATCH M of N] ...", using the first
   line of the changeset description as the subject text. The message contains
   two or three body parts:
   
   - The changeset description.
   - [Optional] The result of running diffstat on the patch.
   - The patch itself, as generated by 'hg export'.
   
   Each message refers to the first in the series using the In-Reply-To and
   References headers, so they will show up as a sequence in threaded mail and
   news readers, and in mail archives.
   
   To configure other defaults, add a section like this to your configuration
   file:
   
     [email]
     from = My Name <my@email>
     to = recipient1, recipient2, ...
     cc = cc1, cc2, ...
     bcc = bcc1, bcc2, ...
     reply-to = address1, address2, ...
   
   Use "[patchbomb]" as configuration section name if you need to override global
   "[email]" address settings.
   
   Then you can use the 'hg email' command to mail a series of changesets as a
   patchbomb.
   
   You can also either configure the method option in the email section to be a
   sendmail compatible mailer or fill out the [smtp] section so that the
   patchbomb extension can automatically send patchbombs directly from the
   commandline. See the [email] and [smtp] sections in hgrc(5) for details.
   
   By default, 'hg email' will prompt for a "To" or "CC" header if you do not
   supply one via configuration or the command line.  You can override this to
   never prompt by configuring an empty value:
   
     [email]
     cc =
   
   You can control the default inclusion of an introduction message with the
   "patchbomb.intro" configuration option. The configuration is always
   overwritten by command line flags like --intro and --desc:
   
     [patchbomb]
     intro=auto   # include introduction message if more than 1 patch (default)
     intro=never  # never include an introduction message
     intro=always # always include an introduction message
   
   You can specify a template for flags to be added in subject prefixes. Flags
   specified by --flag option are exported as "{flags}" keyword:
   
     [patchbomb]
     flagtemplate = "{separate(' ',
                               ifeq(branch, 'default', '', branch|upper),
                               flags)}"
   
   You can set patchbomb to always ask for confirmation by setting
   "patchbomb.confirm" to true.
