refactor text diff/patch code. rename commands.dodiff to patch.diff. rename commands.doexport to patch.export. move some functions from commands to new mercurial.cmdutil module. turn list of diff options into mdiff.diffopts class. patch.diff and patch.export now has clean api for call from 3rd party python code.

merge.

manifest.execf is now a function.

merge.

grep: add --follow support.

grep: display correct user/revision for --all in reverse. Also handle multiple occurrences of the same line by storing linestates in an array instead of a dict, and using difflib to compute the difference between linestates.

util: qualify name properly.

mq: demandload more

commands.import: refactor patch parsing into patch.extract.

merge git patch code.

Tests for git import

Remove debugging line

Fix bad merge with crew

Move patch-related code into its own module.

Teach import to understand git diff extensions. Vanilla patch chokes on git patches that include files that are copied or renamed, then modified. So this code detects that case and rewrites the patch if necessary.

update copyrights.

merge.

Fix some bugs introduced during the manifest refactoring

Fix "hg qnew -f foo" without -m The refresh method assumes it has a string.

merge with mpm.

import: get lock and wlock one time this makes import of many patches 6x faster in kernel repo.

Adjusted documentation for hgrc's "[smtp] host" for change in 9f745d3675d4.

mq: only add mq attribute to local repo

mq: apply patch is any posative guard matches this is like guards command from quilt package.

fetch: fix test fail

mq: do not allow to push from repo with patches applied

call reposetup functions of extension modules whenever repo created
