tests: use pyflakes as a tool, not a python module...
tests: use pyflakes as a tool, not a python module The usage of pyflakes as a Python module was introduced in e397c6d74652, to work around issue between Python 2 and Python 3. This issues are long behind us now and we can get beck to using pyflakes as a tool, giving us more flexibility about how we install it. The `hghave` requirements is modified to check that we have a tool available, instead of a python module.

================================================================
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.
