Interesting point. It used to, when manifestctx would read from the
revlog during the constructor, but since we moved that out, it probably
doesn't now (but probably should). I'll make the manifestctx and
treemanifestctx constructors at least check that the node exists in the
revlog before returning, and throw KeyError if they don't.

manifest: add manifestlog.get to obtain subdirectory instances
Previously manifestlog only allowed obtaining root level manifests. Future
patches will need direct access to subdirectory manifests as part of changegroup
creation, so let's add a get() function that knows how to deal with

nit: Does it really throw KeyError? __getitem__ also doesn't seem to.
