Get rid of the CachedRepo class (almost)

For a long time the CachedRepo class has basically been a wrapper around
the GitDir class, but with a few extra methods that don't really even
belong there.

It is now a tiny class in the localrepocache module which just keeps
track of a few extra attributes. All other functionality is provided
by the gitdir module.

This commit also removes the `git clone` approach for copying repos out
of the cache. The alternative approach implemented by
git.copy_repository() was slightly faster when I tested, so for now we
should use that everywhere. Longer term we should find out why this is
quicker than `git clone`, and fix Git itself to be fast.
