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}.

  http: fix proxy password passing
  http: fix proxy authentication
  http: rename HTTP_REAUTH to HTTP_AUTH_RETRY

  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 Matthieu Moy (6) and others
* mm/push-default-switch-warning:
  fixup! push: introduce new push.default mode "simple"
  fixup! t5528-push-default.sh: add helper functions
  push: suggested updates to push configuration documentation
  push: start warning upcoming default change for push.default
  push: document the future default change for push.default (matching -> simple)
  t5570: use explicit push refspec
  push: introduce new push.default mode "simple"
  t5528-push-default.sh: add helper functions
  Undocument deprecated alias 'push.default=tracking'
  Documentation: explain push.default option a bit more
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.

  run_hook(): enhance the interface to pass arbitrary environment
Merge branch 'th/difftool-diffall' into pu

Merge branch 'rt/cherry-revert-conflict-summary' into pu

In the older days, the header "Conflicts:" in "cherry-pick" and
"merge" was separated by a blank line from the list of paths that
follow for readability, but when "merge" was rewritten in C, we lost
it by mistake. Remove the newline from "cherry-pick" to make them
match again.
