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.

 Some filesystems (notably FAT/exFAT only store timestamps with 2
 seconds of precision, so by sleeping for 3 seconds, we can ensure that
 the timestamps of files stored by dirstate will appear older than the
