[PATCH 03/17] pack-bitmap-write: convert some helpers to use object_id

[Jeff King <peff@xxxxxxxx>]

A few functions take raw hash pointers, but all of their callers
actually have a "struct object_id". Let's retain that extra type as long
as possible (which will let future patches extend that further, and so
on).
