discovery: port _postprocessobsolete() changes from evolve, add tests Let's make this function obsolescence-aware as well. Now we check that revisions are not obsolete first, and only then check that they are going to be common after exchange. The tests make sure that rewriting changesets doesn't confuse head computation. They rely on experimental.single-head-per-branch feature to show that remote correctly sees the expected result (i.e. either aborts the push or allows it to succeed). They are ported from evolve as well. Differential Revision: https://phab.mercurial-scm.org/D12098

 r49537 =========================================
Testing single head enforcement: Case A-3
=========================================
A repository is set to only accept a single head per name (typically named
branch). However, obsolete changesets can make this enforcement more
complicated, because they can be kept visible by other changeset on other
branch.
This case is part of a series of tests checking this behavior.
Category A: Involving obsolescence
TestCase 3: Full superseding of a branch interleaved with another
.. old-state:
..
.. * 2 changesets on branch default
.. * 2 changesets on branch Z interleaved with the other
..
.. new-state:
..
.. * 2 changesets on branch Z at the same location
.. * 2 changesets on branch default superseding the other ones
..
.. expected-result:
..
.. * only one head detected
..
.. graph-summary:
..
.. D ● (branch Z)
.. |
.. C ø⇠◔ C'

.. B ● | (branch Z)
