treemanifests: actually strip directory manifests

Stripping has only partly worked since 7cbb3a01fa38 (repair: use cg3
for treemanifests, 2016-01-19): the bundle seems to have been created
correctly, but revlog entries in subdirectory revlogs were not
stripped. This meant that e.g. "hg verify" would fail after stripping
in a tree manifest repo.

To find the revisions to strip, we simply iterate over all directories
in the repo (included in store.datafiles()). This is inefficient for
stripping few commits, but efficient for stripping many commits. To
optimize for stripping few commits, we could instead walk the tree
from the root and find modified subdirectories, just like we do in the
changegroup code. I'm leaving that for another day.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

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

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
