[PATCH v2 00/10] object_id part 2

This is another series of conversions to struct object_id.

This series converts more of the refs code and struct object to use struct object_id. It introduces an additional helper function, has_object_file, which is the equivalent of has_sha1_file. The name was chosen to be slightly more logical than has_oid_file, although it can be changed if desired.

The next-to-last patch in this series is the conversion of struct object to use struct object_id. This is a necessarily large patch because of the large number of places this code is used. That patch will most likely be too large to make it through to the list, so this series is available in the object-id-part2 branch from:

https://github.com/bk2204/git.git https://git.crustytoothpaste.net/git/bmc/git.git

Changes from v1:
* Rebase on newer master.
* Drop parse_oid_hex.  It ended up not being very useful (only 4 uses
  over 47 patches) and a better version, like the one Michael Haggerty
  suggested, can be introduced later if it's beneficial.
* Fix the code that caused the httpd unit tests to fail.  This series
  passes the testsuite on each commit, including the httpd tests.
* Convert the remaining places touched by the first patch to use
  object_id.  These were split out into their own patches to keep
  patches to a reasonable size.  Some of these were in the original
  series, and some were not.
* Convert remote.c as well.  As part of the previous item, I went
  through remote.c and converted the places touched by the first patch,
  and realized that it was trivial to convert the rest of the file.
  This patch is at the end as we can get slightly better conversion by
  doing it after the conversion of struct object, meaning we can avoid
  making another pass later.  I blame Michael for the inspiration to do
  this. :-)
