Merge branch 'nl/http-proxy-more' into pu

The code to talk to http proxies learn to use the same credential
API used to talk to the final http destinations.  This still needs
to peek into $ENV{HTTPS_PROXY}.

By Nelson Benitez Leon (5) and Jeff King (1)
* nl/http-proxy-more:
  http: fix proxy authentication
  http: rename HTTP_REAUTH to HTTP_AUTH_RETRY
  http: Avoid limit of retrying request only twice
  http: handle proxy authentication failure (error 407)
  http: handle proxy proactive authentication
  http: try http_proxy env var when http.proxy config option is not set
Merge branch 'mm/push-default-switch-warning' into pu

This resurrects an ancient patch I wrote during a discussion we had in the
1.6.3-1.6.4 era.  This should probably come after ct/advise-push-default
topic and at that point the advise messages need to be rephrased, taking
the future default change into account.

By Clemens Buchacher (1) and Matthieu Moy (1)
* mm/push-default-switch-warning:
  t5570: use explicit push refspec
  push: start warning upcoming default change for push.default

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/run-hook-env-1' into pu

Not urgent.

Updates run_hook() API to be much less specific to "commit".  It would
only be useful if people start doing more interesting things with hooks.

* jc/run-hook-env-1:
  run_hook(): enhance the interface to pass arbitrary environment
Merge branch 'th/difftool-diffall' into pu

Rolls the two-directory-diff logic from diffall script (in contrib/) into

Merge branch 'ss/git-svn-prompt-sans-terminal' into pu

The bottom one has been replaced with a rewrite based on comments
from Ævar. The second one needs more work, both in perl/Git.pm and
prompt.c, to give precedence to tty over SSH_ASKPASS when terminal
is available.

Will discard shortly if nothing happens.

* ss/git-svn-prompt-sans-terminal:
  fixup! 15eaaf4
