patch.py: re-add the ability to use an external patch program This is now invoked by default only if ui.patch is set. Otherwise, we use our built-in patch. If that fails because it can't find any valid hunks, we'll fall back to trying the external patch command.

patch.py: don't mark files as changed unless they have actually been changed

patch.py: fix some incorrect uses of _() for i18n

Add Chris Mason's mpatch library. The original repo is http://oss.oracle.com/mercurial/mason/mpatch

convert: manually set encoding to UTF-8 Right now the backends assume we're working in UTF-8 and there's no good way to ignore the encoding when adding revisions.

hg parents: don't pass an OS-specific path to repo.filectx The only reason to use the matcher code instead of calling util.canonpath directly is to be able to use "path:canonical/path/to/file" patterns.
