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 head checking code: Case B-5
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category B: simple case involving pruned changesets
TestCase 5: multi-changeset branch, mix of pruned and superceeded
.. old-state:
..
.. * 3 changeset branch
..
.. new-state:
..
.. * old head is pruned
.. * old mid is superceeded
.. * old root is pruned
..
.. expected-result:
..
.. * push allowed
