obsolescence: add test case A-1 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-1: pushing a single head

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.

check whether HG_PENDING makes pending changes only in relatd
repositories visible to an external hook.

In "hg share" case, another transaction can't run in other
repositories sharing same source repository, because starting
transaction requires locking store of source repository.

Therefore, this test scenario ignores checking visibility of
.hg/bookmakrs.pending in repo2, which shares repo1 without bookmarks.

  $ cat > $TESTTMP/checkbookmarks.sh <<EOF
  > echo "@repo1"
  > hg -R "$TESTTMP/repo1" bookmarks
  > echo "@repo2"
  > hg -R "$TESTTMP/repo2" bookmarks
  > echo "@repo3"
  > hg -R "$TESTTMP/repo3" bookmarks
  > exit 1 # to avoid adding new bookmark for subsequent tests

FYI, in contrast to above test, bmX is invisible in repo1 (= shared
src), because (1) HG_PENDING refers only repo3 and (2)
"bookmarks.pending" is written only into repo3.
