[EGIT PATCH 00/10] Rename support

[Robin Rosenberg <robin.rosenberg@dewire.com>]

This is basically a rewrite. While adding tests to handle some of
the case mentioned in Shawns comments, I had to give up the locking
strategy and go for something more like git, i.e. rename proceeds
in small steps and the I try to undo if a problem is encountered.

Add to that some small enchancments to ref support. Not the big
change we discussed earlier.

The branch command is touched by one of the patches, but it does
not include rename.
