tests: introduce a compat-branches blacklist file

The idea behind this file is to have an easy and obvious mechanism for skipping
some tests on compatibility branches without modifying the test files
themselves or touching .gitlab-ci.yml.

Obviously, each compatibility branch can have different set of tests, and so
the contents of this file can be different on different branches.

This concept had actually existed in core for a long time, see
tests/blacklists/ directory.

=====================================
Testing content-divergence resolution
=====================================

Independent rewrites of same changeset can lead to content-divergence. In most
common cases, it can occur when multiple users rewrite the same changeset
independently and push it.

This test aims to check that the resolution of content-divergent changesets is
independent of the user resolving the divergence. In other words, the two users
resolving the same divergence should end up with the same result.

Setup
-----
  $ . $TESTDIR/testlib/content-divergence-util.sh
  $ setuprepos user-independent-resolution
  creating test repo for test case user-independent-resolution
  - upstream
  - local
  - other
  cd into `local` and proceed with env setup

  $ hg amend -d '2 0' --config devel.default-date='86400 7200'
  $ hg push -q

  $ cd ../local
