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 obsolescence markers push: Cases A.4
============================================

Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).

This test belongs to a series of tests checking such set is properly computed
and applied. this does not tests "obsmarkers" discovery capabilities.

Category A: simple cases
Testcase 4: Push in the middle of the obsolescence chain

A.4 Push in the middle of the obsolescence chain
================================================

.. (Where we show that we should not push the marker without the successors)
..
.. {{{
..   B ◔
..     |
..   A⇠ø⇠○ A'
..     |/
..     ● O
.. }}}
..
.. Markers exist from:
..
..  * `A ø⇠○ A'`
..  * chain from A
..
.. Command runs:
..
..  * hg push -r B
..
.. Expected exchange:
..
..  * Chain from A
..
.. Expected Exclude:
..
..  * `Ai ø⇠○ A'`
