Merge branch 'jc/test-lib-source-build-options-early' into pu

Reorders t/test-lib.sh so that we dot-source GIT-BUILD-OPTIONS that
records the shell and Perl the user told us to use with Git a lot
early, so that test-lib.sh script itself can use "$PERL_PATH" in
one of its early operations.

Needs to be eyeballed by people who run tests with exotic options
like valgrind, --root=/dev/shm/somewhere, etc.

* jc/test-lib-source-build-options-early:
  test-lib: reorder and include GIT-BUILD-OPTIONS a lot earlier

Merge branch 'jc/split-blob' into pu

Not ready.

I finished the streaming checkout codepath, but as explained in
127b177 (bulk-checkin: support chunked-object encoding, 2011-11-30),
these are still early steps of a long and painful journey. At least
pack-objects and fsck need to learn the new encoding for the series
to be usable locally, and then index-pack/unpack-objects needs to
learn it to be used remotely.

Given that I heard a lot of noise that people want large files, and
that I was asked by somebody at GitTogether'11 privately for an
advice on how to pay developers (not me) to help adding necessary
support, I am somewhat dissapointed that the original patch series
that was sent almost two months ago still remains here without much
comments and updates from the developer community. I even made the
interface to the logic that decides where to split chunks easily
replaceable, and I deliberately made the logic in the original patch
extremely stupid to entice others, especially the "bup" fanboys, to
come up with a better logic, thinking that giving people an easy
target to shoot for, they may be encouraged to help out. The plan is
not working :-(.

* jc/split-blob:
  chunked-object: streaming checkout
  chunked-object: fallback checkout codepaths
  bulk-checkin: support chunked-object encoding

Merge branch 'jc/maint-push-refs-all' into pu

Allows pushing and fetching refs/stash.
There still seem to be other bugs hiding (e.g. try pushing twice).

Merge branch 'lt/commit-tree-guess-utf-8' into pu

Teaches "git commit" and "git commit-tree" the "we are told to use
utf-8 in log message, but this does not look like utf-8---attempt to
pass it through convert-from-latin1-to-utf8 and see if it makes
sense" heuristics "git mailinfo" already uses.

A draft from Linus received privately without a log message.
Hopefully it will be rerolled.
