[PATCH] Remove "delta" object representation.

Packed delta files created by git-pack-objects seems to be the
way to go, and existing "delta" object handling code has exposed
the object representation details to too many places.  Remove it
while we refactor code to come up with a proper interface in
sha1_file.c.
