lazy_import most things in merge.py; add a few representative modules to the import tariff tests; tweak a couple of other modules so that patiencediff is not necessarily imported; remove a bunch of unused imports from test_knit.py.

* Use lazy imports in ``bzrlib/merge.py`` so that plugins like ``news_merge``
 
36
  do not cause modules to be loaded unnecessarily just because the plugin
 
37
  registers a merge hook.  This improves ``bzr rocks`` time by about 25%
 
38
  in a default installation (with just the core plugins).

* ``bzrlib.knit.KnitSequenceMatcher``, which has been deprecated since
 
54
  2007, has been deleted.  Use ``PatienceSequenceMatcher`` from
 
55
  ``bzrlib.patiencediff`` instead.
