manifest: add support for including directories outside narrowspec
When using tree manifests and the client doesn't have a directory, we
have two choices for what to do with "hg manifest" output: 1) ignore
the directory, and 2) include the directory (not files within it). For
"hg files", we decided to ignore the directories (and files) outside
the narrowspec.
If we choose to not include directories outside the narrowspec, then I
think we should also make sure we don't include files outside the
narrowspec. I also think we should add --outside-narrow flag (or other
name). Thus, whichever way we go, I think we should have a way of
displaying paths (files or directories) outside the narrowspec. For
that we'll need to handle the 't' flag that narrowhg uses, and that's
what this patch adds support for.

narrow: restrict manifest iteration by using manifest.walk(matcher)
This is only for root nodes, so it shouldn't really matter (they're
rarely huge), but seems cleaner.

narrow: only diff manifest part within narrowspec when generating changegroup
Since
959ebff3505a (manifest: add match argument to diff and
filesnotin, 2017-03-07), we have a more efficient way of diffing
manifests while applying a matcher. Let's use that while generating
narrowed changegroups, so we avoid diffing parts of the manifest that
don't match the narrowspec.
