rust: add Debug constraint to Matcher trait

This makes sure we can easily debug which Matcher we're looking at when using
trait objects, and is just generally useful. Effort to make the debugging
output nicer has been kept to a minimum, please feel free to improve.

====================================
Testing head checking code: Case B-3
====================================

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TestCase 3: multi-changeset branch, other is pruned, rest is superseded

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is superseded
.. * old other is pruned
..
.. expected-result:
..
.. * push allowed

  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  new changesets d73caddc5533 (1 drafts)
  (run 'hg update' to get a working copy)
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
