addremove: don't do full walks

Full walks are only necessary when the caller needs the list of clean files.
addremove by definition doesn't need them.

With this patch and an extension that produces a subset of results for
dirstate.walk when full is False, on a repository with over 200,000 files, hg
addremove drops from 2.8 seconds to 0.5.
