manifest: throw LookupError if node not in revlog

When accessing a manifest via manifestlog[node], let's verify that the node
actually exists and throw a LookupError if it doesn't. This matches the old read
behavior, so we don't accidentally return invalid manifestctxs.

We do this in manifestlog instead of in the manifestctx/treemanifestctx
constructors because the treemanifest code currently relies on the fact that
certain code paths can produce treemanifests without touching the revlogs (and
it has tests that verify things work if certain revlogs are missing entirely, so
they break if we add validation that tries to read them).

# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
