[PATCHv1,0/3] git-p4: improved unshelving

Message

This patch series teaches the git-p4 unshelve command to handle
intervening changes to the Perforce files.

At the moment if you try to unshelve a file, and that file has been
modified since the shelving, git-p4 refuses. That is so that it
doesn't end up generating a commit containing deltas from several P4
changes.

This gets to be more annoying as time goes on and the files you are
interested in get updated by other people.

However, what we can do is to create a parent commit matching the
state of the tree when the shelve happened, which then lets git-p4
create a git commit containing just the changes that are wanted.

It's still impossible to determine the true state of the complete
tree when the P4 shelve was created, since this information is not
recorded by Perforce. Manual intervention is required to fix that.

There are also a few other smaller fixes, the main one being
that it no longer unshelves into refs/remotes/p4/master/unshelved, but
instead into refs/remotes/p4-unshelved.

That's because the git-p4 branch detection gets confused by branches
appearing in refs/remotes/p4.
