run-tests: add --rev to run tests with specific version of hg
This is mostly designed for use outside of hg.
If you want to run tests based on the version of Mercurial you're
targeting, you will probably need a wrapper test, as seen in the
tests provided with this commit.
* We can not use "archive" because the version information is lost.
* We have to include the tag commit too, otherwise the version
calculation will mess up.
* Old versions of mercurial don't necessarily support the repo format
that the current repo has, so we have to blacklist any unsupported
features.
* Certain versions of mercurial choke on the obsstore format, so we
remove it.
