[RFC][PATCH 0/7] Submodule support in git mv, git rm

[Petr Baudis <pasky@suse.cz>]

The following series implements submodule support in git mv and git rm,
plus enhancing the submodules testsuite a bit. I'd appreciate comments,
especially on the git mv change, since the index_path_src_sha1 is
really a horrible hack.

The pinnacle of this series was supposed to be merge-recursive support
for submodule-somethingelese conflicts, however that seems a bit more
complicated than I expected, so I decided to first send the rest for
a review.
