relnotes: skip the test if the source repository is not readable

The test want to run the relnot extension, with the tested mercurial, on the
original repository. This is not always possible (e.g. when running with --pure
and the repository use zstd for example). So we skip the test in this case.

================================================================
test the interaction of the branch cache with obsolete changeset
================================================================

Some corner case have been covered by unrelated test (like rebase ones) this
file meant to gather explicite testing of those.

Setup graph

graph with a single branch

We want some branching and some obsolescence

  $ mkcommit A_2
  $ hg update 'desc("A_2")' --quiet
  $ mkcommit B_1
  $ mkcommit B_2
  $ mkcommit B_3
  $ mkcommit B_4
  $ hg update 'desc("A_2")' --quiet
  $ mkcommit A_3
  created new head
  $ mkcommit A_4
  $ hg up null --quiet
  $ hg clone --noupdate . ../main-single-branch-pre-ops
  $ hg log -r 'desc("A_1")' -T '{node}' > ../main-single-branch-node_A1
  $ hg log -r 'desc("A_2")' -T '{node}' > ../main-single-branch-node_A2
