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.

hg pick with no active topic and with a different active topic (issue6406)

This is what the help text says about this issue

  $ hg help pick | grep 'active topic' | sed 's/^    //'
  The resulting changeset will have the current active topic. If there's no
  active topic set, the resulting changeset will also not have any topic.

wdir has no active topic: pick should clear topic of the resulting cset

  $ hg debug-topic-namespace --clear
  $ hg topic --clear
  $ hg pick 'desc("banana")'
  picking 2:fcda3d8dafd2 "banana"
  1 new orphan changesets
  $ hg log -r . -T '{rev}: {desc} ({fqbn})\n'
  4: banana (default)
  $ hg debug-topic-namespace
  none
  $ hg topic --current
  no active topic
  [1]

wdir has active topic: pick should use the active topic for the resulting cset

  $ hg debug-topic-namespace everything
  marked working directory as topic namespace: everything
  $ hg topic all-things
  marked working directory as topic: all-things
  $ hg pick 'desc("blackberry")'
  picking 3:48bbfbece8fa "blackberry"
  active topic 'all-things' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg log -r . -T '{rev}: {desc} ({fqbn})\n'
  5: blackberry (default//everything/all-things)
  $ hg debug-topic-namespace

  $ hg topic --current
  all-things

  $ hg log -GT '{rev}: {desc} ({fqbn})\n{join(extras, " ")}\n\n'
