Series of steps:
* Create a local "b1" branch with `repo start b1` that tracks a remote
branch (totally fine)
* Manually create a local "b2" branch with `git branch --track b1 b2`
that tracks the local "b1" (uh-oh...)
* Delete the local "b1" branch manually or via `repo prune` (....)
* Try to process the "b2" branch with `repo prune`
Since b2 tracks a branch that no longer exists, everything blows up
at this point as we try to probe the non-existent ref. Instead, we
should flag this as unknown and leave it up to the user to resolve.
This probably could come up if a local branch was tracking a remote
branch that was deleted from the server, and users ran something like
`repo sync --prune` which cleaned up the remote refs.

As we convert repo to support Python 3, the version of Python that we
use might not be the version that repo hooks users have written for.
Since repo upgrades are not immediate, and not easily under direct
control of end users (relative to the projects maintaining the hook
code), allow hook authors to declare the version of Python that they
want to use.
Now repo will read the shebang from the hook script and compare it
against the version of Python repo itself is running under. If they
differ, we'll try to execute a separate instance of Python and have
it load & execute the hook. If things are compatible, then we still
use the inprocess execution logic that we have today.
This allows repo hook users to upgrade on their own schedule (they
could even upgrade to Python 3 ahead of us) without having to worry
about their supported version being exactly in sync with repo's.
