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 in just a 'visitdir(dir)'
callback, but the results did not seem better overall. I'm happy to
update if anyone has better ideas.

#require test-repo execbit

  $ cd "`dirname "$TESTDIR"`"

look for python scripts without the execute bit

  $ hg files 'set:**.py and not exec() and grep(r"^#!.*?python")'

look for python scripts with execute bit but not shebang

  $ hg files 'set:**.py and exec() and not grep(r"^#!.*?python")'

look for shell scripts with execute bit but not shebang

  $ hg files 'set:**.sh and exec() and not grep(r"^#!.*(ba)?sh")'

look for non scripts with no shebang

  $ hg files 'set:exec() and not **.sh and not **.py and not grep(r"^#!")'
