Refactor diffrevs/diffdir into changes

Refactor diffrevs/diffdir into changes

Add dirstate.changes to replace most of diffdir
Add localrepository.changes to replace diffrevs/diffdir

This code can now efficiently check for changes in single files, and
often without consulting the manifest. This should eventually make 'hg
diff Makefile' in a large project much faster.

This also fixes a bug where 'hg diff -r tip' failed to account for
files that had been added but not committed yet.
