Before this patch, there were two code paths: either getting the only
the wanted content by calling git-archive, or cloning the repository and
copying the files.
Both these approaches have the downside of not allowing retriving
content from a specific git commit.
The workaround is to create a new empty repo (in the location to which
we cloned previously), fetching the specific commit to there and then
checking it out.
This supports any commit and works identically for any protocol. The
downside is that all files in that commit will be downloaded. It should
be no worse than the git-clone path, but can result in bigger transfers
than git-archive.
Unfortunately this is only supported with git 2.5+. On older version
fetch will fail with no error message (tested with 1.8.3). This can be
used to fall back to full clone. This fallback is clearly suboptimal in
terms of data transfer, but it should work reliably.

RHEL has an older version of the library which does not backport all the
assertions that we used. In order for the tests to pass there we need to
use names that exist everywhere.

This should make all tests pass on both Python 2 and Python 3.
Unittest2 is required on Py 2.6 and Py 3.

When a file should be obtained from a git repository, allow running an
arbitrary command (like `make`) after clone but before copying the files
out. This only works for the Git backend.
The downside is that a clone is needed and we can no longer use `git
archive` to speed things up.

The module backports features to Python 2.6 and 2.7. If it is available,
the tests will use it. If it is not available, it will fall back to
regular unittest. On Python 2.7, the tests pass anyway. On Python 2.6,
there are failures with Python 2.6.

Instead of spawning `cp x/* y` there is now Python code to the same
thing. This should help with debugging if something fails as the
traceback will be more informative (rather than saying a command
failed). As another benefit the tests get much simpler.
