bundlerepo: add support for treemanifests in cg3 bundles

This is a little messier than I'd like, and I'll probably come back
and do some more refactoring later, but as it is this unblocks
narrowhg. An alternative approach (which I may do as part of the
mentioned refactoring) would be to construct *all* dirlog instances up
front, so that we don't have to keep track of the linkmapper
method. This would avoid a reference cycle between the bundlemanifest
and the bundlerepository, but I was hesitant to do all the work up
front like that.

With this change, it's possible to do 'hg incoming' and 'hg pull' from
bundles in .hg/strip-backup in a treemanifest repository. Sadly, this
doesn't make it possible to 'hg clone' one of those (if you do 'hg
strip 0'), because the cg3 in the bundle gets written without a
treemanifest flag. Since that's going to be an involved refactor in a
different part of the code (which I *suspect* won't touch any of the
code I've just written here), let's leave it as an idea for Later.

Source bundle was generated with the following script:

# hg init
# echo a > a
# ln -s a l
# hg ci -Ama -d'0 0'
# mkdir b
# echo a > b/a
# chmod +x b/a
# hg ci -Amb -d'1 0'

  $ hg init
  $ hg -q pull "$TESTDIR/bundles/test-manifest.hg"

The next call is expected to return nothing:

  $ hg manifest

  $ hg co
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg manifest
  a
  b/a
  l

  $ hg files -vr .
           2   a
           2 x b/a (glob)
           1 l l
  $ hg files -r . -X b
  a
  l

  $ hg manifest -v
  644   a
  755 * b/a
  644 @ l

  $ hg manifest --debug
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 644   a
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 755 * b/a
  047b75c6d7a3ef6a2243bd0e99f94f6ea6683597 644 @ l

  $ hg manifest -r 0
  a
  l

  $ hg manifest -r 1
  a
  b/a
  l

  $ hg manifest -r tip
  a
  b/a
  l

  $ hg manifest tip
  a
  b/a
  l

  $ hg manifest --all
  a
  b/a
  l

The next two calls are expected to abort:

  $ hg manifest -r 2
  abort: unknown revision '2'!
  [255]

  $ hg manifest -r tip tip
  abort: please specify just one revision
  [255]
