[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.

-SYNOPSIS
---------
-'git-mkdelta' [-v] [-d N | --max-depth=N ] <reference_object> <target_object> [ <next_object> ... ]
-
-DESCRIPTION
------------
-Creates a delta object to replace <reference_object> by using an
-ordered list of potential objects to deltafy against earlier objects
-in the list.
-
-A cap on the depth of delta references can be provided as well,
-otherwise the default is to not have any limit.  A limit of 0 will
-also undeltafy a given object.
-
-
-OPTIONS
--------
--v::
-	Verbose
-
--d|--max-depth::
-	limit the number of delta references in a chain
-	If 0 then all objects are undeltafied.
