support hooks written in python.

to write hook in python, create module with hook function inside.
make sure mercurial can import module (put it in $PYTHONPATH or load it
as extension).  hook function should look like this:

def myhook(ui, repo, hooktype, **kwargs):
   if hook_passes:
      return True
   elif hook_explicitly_fails:
      return False
   elif some_other_failure:
      import util
      raise util.Abort('helpful failure message')
   else:
      return
      # implicit return of None makes hook fail!

then in .hgrc, add hook with "python:" prefix:

[hooks]
commit = python:mymodule.myhook

#!/bin/sh

hg init
echo a > a
hg add a
hg commit -m "1" -d "1000000 0"
hg status
hg copy a b
hg status
hg --debug commit -m "2" -d "1000000 0"
echo "we should see two history entries"
hg history -v
echo "we should see one log entry for a"
hg log a
echo "this should show a revision linked to changeset 0"
hg debugindex .hg/data/a.i
echo "we should see one log entry for b"
hg log b
echo "this should show a revision linked to changeset 1"
hg debugindex .hg/data/b.i

echo "this should show the rename information in the metadata"
hg debugdata .hg/data/b.d 0 | head -3 | tail -2

$TESTDIR/md5sum.py .hg/data/b.d
hg cat b > bsum
$TESTDIR/md5sum.py bsum
hg cat a > asum
$TESTDIR/md5sum.py asum
hg verify
