tests: add tests of pathcopies()
I'm working on support for storing copy metadata in the changeset
instead of in the filelog. When storing it in the changeset, it will
obviously be efficient to get the copy metadata for all files in a
single changeset, but it will be more expensive to get the copy
metadata all revisions of a single file. Some algorithms will then
need to be optimized differently. The first method I'm going to
rewrite is pathcopies().
This commit adds many tests for pathcopies(), so we can run the tests
with both old and new versions of the code, as well as with metadata
stored in filelog or in changeset (later). They use the
debugpathcopies command I recently added (with no tests when it was
added). They show a few bugs and few cases of slightly weird
behavior. I'll fix the bugs in the next few commits.

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
--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)
