Add flags for enabling --delta computation.

Something isn't 100% correct, because post-filter we end up with different counts.
The performance is pretty darn good, though.
[--filter] Took 4.184s for 100 revisions (610 changes, 88005 file_ids) and path: bzrlib
vs
Took 0.702s for 100 revisions (599 changes, 88005 file_ids) and path: bzrlib
vs
[--filter] Took 3.268s for 100 revisions (0 changes, 88005 file_ids) and path: bzrlib
and
Took 0.288s for 100 revisions (0 changes, 88005 file_ids) and path: bzrlib
Note also that iter_changes is faster in the chk form, than the pre-filtered form.
Not huge, but 0.7-0.28 = 0.414, vs 4.184-3.268=0.916.

Start working on some code to expand a path into a bunch of file-ids that
represent that path.

Initial results are pretty promising over the existing 'inventory.filter()' code path.
For 2000 mainline revs of bzr looking at all of bzrlib, it took 3.3s vs 54.7 for --filter.

Change to expand using the chk expansion logic.

I don't think the logic is perfect, but we at least know it matches
the filter() logic.
