tests: add support for emitting trace events to run-tests
Right now this is pretty basic, but it's a start.

====================================
Testing head checking code: Case B-7
====================================
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 7: single changesets, pruned then superseeded (on an existing changeset)
.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old branch is rewritten onto the common set,
.. * the new version is then pruned.

updating to branch default
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd client
$ hg up 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit B0
created new head
$ mkcommit A1
$ hg up 'desc(B0)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg debugobsolete `getid "desc(A0)"` `getid "desc(A1)"`
