obsolescence: add test case A-2 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 A-2: Two heads, only one of them pushed
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.

WiX installer source files
==========================
The files in this folder are used by the thg-winbuild [1] package
building architecture to create a Mercurial MSI installer. These files
are versioned within the Mercurial source tree because the WXS files
must kept up to date with distribution changes within their branch. In
other words, the default branch WXS files are expected to diverge from
the stable branch WXS files. Storing them within the same repository is
the only sane way to keep the source tree and the installer in sync.
The MSI installer builder uses only the mercurial.ini file from the
contrib/win32 folder, the contents of which have been historically used
to create an InnoSetup based installer. The rest of the files there are
ignored.
The MSI packages built by thg-winbuild require elevated (admin)
privileges to be installed due to the installation of MSVC CRT libraries
under the C:\WINDOWS\WinSxS folder. Thus the InnoSetup installers may
still be useful to some users.
To build your own MSI packages, clone the thg-winbuild [1] repository
and follow the README.txt [2] instructions closely. There are fewer
prerequisites for a WiX [3] installer than an InnoSetup installer, but
they are more specific.
