* erepo: cache all read only external repos by hexsha

So we have 3 things cached now separately:
- clean clones, to not ask for creds repatedly
- cache dirs, also shared between erepos with same origin
- checked out clones if they are read only, addressed by (url, hexsha)

Several additions to `Git` along the way:
- Git.is_sha() static method
- .pull() and .push() work with multiple returned records correctly
- .get_rev() and .resolve_rev() work faster
- .resolve_rev() looks for remote branches
- .has_rev()

Fixes #3280.

* git: improve .resolve_rev()

It follows `git checkout` logic now - if name can be unambiguously
resolved across known remotes then it's done.
