verify: show progress while verifying dirlogs

In repos with treemanifests, the non-root-directory dirlogs often have
many more total revisions than the root manifest log has. This change
adds progress out to that part of 'hg verify'. Since the verification
is recursive along the directory tree, we don't know how many total
revisions there are at the beginning of the command, so instead we
report progress in units of directories, much like we report progress
for verification of files today.

I'm not very happy with passing both 'storefiles' and 'progress' into
the recursive calls. I tried passing just a 'visitdir(dir)' callback
in, but the results did not seem better overall. I'm happy to update
if anyone has better ideas.
