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
  bulk-checkin: allow the same data to be multiply hashed
  new representation types in the packstream
  packfile: use varint functions

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).

Not ready.

* jc/maint-push-refs-all:
  get_fetch_map(): tighten checks on dest refs
  fetch/push: allow refs/*:refs/*
Merge branch 'jk/no-op-push-message' into pu

Rewords the status message of "git push" that pushed only one ref
differently from "Everything up-to-date", to give a bit more help to
people who get the message when their current branch is not pushed.

I had an impression after the discussion thread that a redesign is
coming, but it hasn't happened yet.

Will discard without prejudice, unless rerolled.

# By Jeff King
* jk/no-op-push-message:
  improve no-op push output
Merge branch 'nl/http-proxy-more' into pu

I queued only the later two patches from this series, even though they do
not make much sense without the first one that seems to need a bit more
work, so that we won't forget.

Will discard without prejudice, unless rerolled.

# By Jeff King (1) and Nelson Benitez Leon (1)
* nl/http-proxy-more:
  http: rename HTTP_REAUTH to HTTP_AUTH_RETRY
  http: Avoid limit of retrying request only twice
Merge branch 'tb/sanitize-decomposed-utf-8-pathname' into pu

Teaches git to normalize pathnames read from readdir(3) and all
arguments from the command line into precomposed UTF-8 (assuming
that they come as decomposed UTF-8) to work around issues on Mac OS.

I think there still are other places that need conversion
(e.g. paths that are read from stdin for some commands), but this
should be a step in the right direction.

Will merge to 'next'.

Merge branch 'cw/no-detaching-an-unborn' into pu

"git checkout --detach" when you are still on an unborn branch
should be forbidden, but it wasn't.
