[PATCH 104/194] object: add repository argument to parse_object_buffer

[Stefan Beller <sbeller@google.com>]

Add a repository argument to allow the callers of parse_object_buffer
to be more specific about which repository to act on. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.

Add the cocci patch that converted the callers.
