[patch 01/10] dirstate walking optimizations

Here's an updated version of the dirstate optimization. Before, both
dirstate.changes and dirstate.walk would make a copy of the map. I've
changed dirstate.changes to pass the map it creates to dirstate.walk.
This required a small change to the traverse function so that it doesn't
delete items from the map anymore.
Also, dirstate.filterfiles now optimistically assumes each file passed exists
in the map. This is the common case, and brings the time for hg diff
Makefile down from .3s to .2s. Not a big difference for that one call, but
the total time to apply 600 patches goes down from 2m to 1m30s.
