parsers: add a C function to pack the dirstate This is about 9 times faster than the Python dirstate packing code. The relatively small speedup is due to the poor locality and memory access patterns caused by traversing dicts and other boxed Python values.

test-convert: disable autocrlf for git

debugwalk: observe ui.slash config option

test-commit: remove extra cd .. This specific cd .. leaves the base directory of the test ($TESTTMP). Removing it avoids that test artifacts (e.g. files) are created outside of the base directory.

merge with stable

notify: various fixes to docstring Typo corrections, grammar adjustments, clarity improvements.

help: sort results from keyword search

tests: reintroduce globs in test-convert-authormap.t They are needed on windows and were accidentally removed in eaf6a6d7f015.

tests: removed unneeded section in acl configuration: 'extensions' Declaring 'acl' in the [extensions] section doesn't change anything.

config: use util.compilere to compile regexps

matcher: use re2 bindings if available There are two sets of Python re2 bindings available on the internet; this code works with both. Using re2 can greatly improve "hg status" performance when a .hgignore file becomes even modestly complex. Example: "hg status" on a clean tree with 134K files, where "hg debugignore" reports a regexp 4256 bytes in size. no .hgignore: 1.76 sec Python re: 2.79 re2: 1.82 The overhead of regexp matching drops from 1.03 seconds with stock re to 0.06 with re2. (For comparison, a git repo with the same contents and .gitignore file runs "git status -s" in 1.71 seconds, i.e. only slightly faster than hg with re2.)

help: fix extension commands help in keyword search This patch fixes the synopsis shown for extension commands in keyword search results. A previous patch erroneously caused the extension synopsis to be shown instead. Test cases for keyword search are missing, so I added a one.
