wireprotov2: advertise recognized path filter prefixes

While the wire protocol doesn't yet support it, we'll eventually
have commands that accept narrow patterns to specify the set of
files relevant to a command.

For security and performance reasons, only specific filter types
are allowed.

This commit teaches the server to advertise the set of allowed
filter types. By doing so, clients can e.g. validate user-specified
patterns against the server's abilities without having to send
a command to retrieve data.

Having the data in the capabilities data structure will also serve
as a check against unwanted BC.

Test for showing working of allfiles flag

  $ hg grep -r "." "unmod" --all-files

With --all-files, the working directory is searched by default

  $ echo modified >> new
  $ hg grep --all-files mod
  new:modified
  um:unmod

 which can be overridden by -rREV

  $ hg grep --all-files -r. mod
  um:1:unmod

commands.all-files can be negated by --no-all-files

  $ hg grep --config commands.grep.all-files=True mod
  new:modified

  $ hg grep --config commands.grep.all-files=True --no-all-files mod
  um:0:unmod

--diff --all-files makes no sense since --diff is the option to grep history

  $ hg grep --diff --all-files um
  abort: --diff and --all-files are mutually exclusive
