obsolescence: add test case D-4 for obsolescence markers exchange
About 3 years ago, in August 2014, the logic to select what markers to select on
push was ported from the evolve extension to Mercurial core. However, for some
unclear reasons, the tests for that logic were not ported alongside.
I realised it a couple of weeks ago while working on another push related issue.
I've made a clean up pass on the tests and they are now ready to integrate the
core test suite. This series of changesets do not change any logic. I just adds
test for logic that has been around for about 10 versions of Mercurial.
They are a patch for each test case. It makes it easier to review and postpone
one with documentation issues without rejecting the wholes series.
This patch introduce case D-4: unknown changeset in between known on
Each test case comes it in own test file. It help parallelism and does not
introduce a significant overhead from having a single unified giant test file.
Here are timing to support this claim.

============================================
Testing obsolescence markers push: Cases D.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 D: Partial Information Case
TestCase 4: Unknown changeset in between known changesets
D.4 Unknown changeset in between known one
