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.
