narrow: add option for automatically removing unused includes
It's been a somewhat common request among our users to have Mercurial
automatically pick includes to remove. This patch adds an option for
that: `hg tracked --auto-remove-includes`. I'm not sure if this is the
right name and semantics for it. Perhaps the feature should also add
excludes of large subdirectories even if other files in the include
are needed? Narrow clones are experimental, so we can change the name
and/or semantics later if necessary.

Testing the --import-rules flag of `hg tracked` command
$ cd narrow
$ hg tracked --import-rules
hg tracked: option --import-rules requires argument
hg tracked [OPTIONS]... [REMOTE]
show or change the current narrowspec
options ([+] can be repeated):
--addinclude VALUE [+] new paths to include
--removeinclude VALUE [+] old paths to no longer include
--auto-remove-includes automatically choose unused includes to
remove
--addexclude VALUE [+] new paths to exclude
--import-rules VALUE import narrowspecs from a file
--removeexclude VALUE [+] old paths to no longer exclude
--clear whether to replace the existing narrowspec
--force-delete-local-changes forces deletion of local changes when
narrowing
--update-working-copy update working copy when the store has
changed
-e --ssh CMD specify ssh command to use
--remotecmd CMD specify hg command to run on the remote side
--insecure do not verify server certificate (ignoring
web.cacerts config)
(use 'hg tracked -h' to show more help)
