revbranchcache: disable mmap access by default

The revbranchcache can be truncated (if some part of it is detected as invalid).
Using mmap on file we truncate is not an option at access to truncated part
would result in a SIGBUS signal.

So we disable the mmap by default until we fix this issue.

 # configitems.toml - centralized declaration of configuration options
 #
 # This file contains declarations of the core Mercurial configuration options.
 #
 # # Structure
 #
 # items: array of config items
 # templates: mapping of template name to template declaration
 # template-applications: array of template applications
 #
 # # Elements
 #
 # ## Item
 #
 # Declares a core Mercurial option.
 #
 # - section: string (required)
 # - name: string (required)
 # - default-type: boolean, changes how `default` is read
 # - default: any
 # - generic: boolean
 # - priority: integer, only if `generic` is true
 # - alias: list of 2-tuples of strings
 # - experimental: boolean
 # - documentation: string
 # - in_core_extension: string
 #
 # ## Template
 #
 # Declares a group of options to be re-used for multiple sections.
 #
 # - all the same fields as `Item`, except `section` and `name`
 # - `suffix` (string, required)
 #
 # ## Template applications
 #
 # Uses a `Template` to instanciate its options in a given section.
 #
 # - template: string (required, must match a `Template` name)
 # - section: string (required)

 #
 # * include management of a persistent nodemap in the main docket
 # * enforce a "no-truncate" policy for mmap safety
 #      - for censoring operation
 #      - for stripping operation
 #      - for rollback operation
 # * proper streaming (race free) of the docket file
 # * track garbage data to evemtually allow rewriting -existing- sidedata.
 # * Exchange-wise, we will also need to do something more efficient than
 #   keeping references to the affected revlogs, especially memory-wise when
 #   rewriting sidedata.
 # * introduce a proper solution to reduce the number of filelog related files.
 # * use caching for reading sidedata (similar to what we do for data).
 # * no longer set offset=0 if sidedata_size=0 (simplify cutoff computation).
 # * Improvement to consider
 #   - avoid compression header in chunk using the default compression?
 #   - forbid "inline" compression mode entirely?
 #   - split the data offset and flag field (the 2 bytes save are mostly trouble)
 #   - keep track of uncompressed -chunk- size (to preallocate memory better)
 #   - keep track of chain base or size (probably not that useful anymore)
