Merge branch 'kb/fast-hashmap' into pu

Improvements to our hash table to get it to meet the needs of the
msysgit fscache project, with some nice performance improvements.

The tip one does not seem to have reached concensus (yet).

* kb/fast-hashmap:
  hashmap.h: make sure map entries are tightly packed
Merge branch 'rv/send-email-cache-generated-mid' into pu

  gitweb: Make feed title valid utf8
  gitweb: Fix utf8 encoding for blob_plain, blobdiff_plain, commitdiff_plain, and patch
Merge branch 'jc/format-patch' into pu

A new option to send a single patch to the standard output to be
appended at the bottom of a message.  I personally have no need for
this, but it was easy enough to cobble together.  Tests, docs and
stripping out more MIMEy stuff are left as exercises to interested
parties.

* jc/format-patch:
  format-patch: --inline-single
  format-patch: rename "no_inline" field

# Conflicts:
# 	builtin/log.c
# 	log-tree.c
# 	pretty.c
Merge branch 'jc/show-branch' into pu

* jc/show-branch:
  show-branch: use commit slab to represent bitflags of arbitrary width
  show-branch.c: remove "all_mask"
  show-branch.c: abstract out "flags" operation
  show-branch.c: lift all_mask/all_revs to a global static
  show-branch.c: update comment style

# Conflicts:
# 	builtin/show-branch.c
Merge branch 'rj/read-default-config-in-show-ref-pack-refs' into pu

The changes themselves are probably good, but it is unclear what
basic setting needs to be read for which exact operation.

$gmane/228294

* rj/read-default-config-in-show-ref-pack-refs:
  ### DONTMERGE: needs better explanation on what config they need
  pack-refs.c: Add missing call to git_config()
  show-ref.c: Add missing call to git_config()
Merge branch 'tr/merge-recursive-index-only' into pu

Will hold until using script appears.

  merge-recursive: -Xindex-only to leave worktree unchanged
  merge-recursive: internal flag to avoid touching the worktree
  merge-recursive: remove dead conditional in update_stages()
Merge branch 'tg/perf-lib-test-perf-cleanup' into pu

Add test_perf_cleanup shell function to the perf suite, that allows
the script writers to define a test with a clean-up action.

Holding until needed.

* tg/perf-lib-test-perf-cleanup:
  perf-lib: add test_perf_cleanup target
  perf-lib: split starting the test from the execution
Merge branch 'yt/shortened-rename' into pu

Attempts to give more weight on the fact that a filepair represents
a rename than showing substring of the actual path when diffstat
lines are not wide enough.

I am not sure if that is solving a right problem, though.

* yt/shortened-rename:
  SQUASH??? style fixes and s/omit/shorten/ where appropriate
  diff.c: keep arrow(=>) on show_stats()'s shortened filename part to make rename visible
Merge branch 'jt/commit-fixes-footer' into pu

There is an ongoing discussion around this topic; in general I am
fairly negative on a new feature that is too narrow and prefer a
more generic solution that can be tailored for specific needs, as
many people stated in the thread.

It appears that the discussion stalled.

* jt/commit-fixes-footer:
  commit: Add -f, --fixes <commit> option to add Fixes: line
Merge branch 'jc/create-directories-microopt' into pu

Of unknown value until tested on non-Linux platforms (especially
Windows).

Will hold.

* jc/create-directories-microopt:
  checkout: most of the time we have good leading directories
Merge branch 'fp/submodule-checkout-mode' into pu

* fp/submodule-checkout-mode:
  DONOTMERGE: needs sign-off
  git-submodule.sh: support 'checkout' as a valid update mode
### Reported/known to be broken

SZEDER Gábor noticed that this breaks "git -c var=val alias" and
also suggested a better description of the change.

Will hold.
