dirstate: make dir collision logic faster

- shortcircuit decpath if we haven't built the _dirs map
- increment only for leafnodes of directory tree
  (this should make construction more like O(nlog n) than O(n^2))

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help
