manifest: move revlog specific options from manifest to manifestrevlog

The manifestv2 and treeondisk options are specific to how we serialize the
manifest into revlogs, so let's move them onto the manifestrevlog class. This
will allow us to add a manifestlog.add() function in a future diff that will
rely on manifestrevlog to make decisions about how to serialize the given
manifest to disk.

We have to move a little bit of extra logic about the 'dir' as well, since it is
used in conjunction with the treeondisk option to decide the revlog file name.
It's probably good to move this down to the manifestrevlog class anyway, since
it's specific to the revlog.

#require test-repo execbit

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ cd "`dirname "$TESTDIR"`"

look for python scripts without the execute bit

  $ hg files 'set:**.py and not exec() and grep(r"^#!.*?python")'

look for python scripts with execute bit but not shebang

  $ hg files 'set:**.py and exec() and not grep(r"^#!.*?python")'

look for shell scripts with execute bit but not shebang

  $ hg files 'set:**.sh and exec() and not grep(r"^#!.*(ba)?sh")'

look for non scripts with no shebang

  $ hg files 'set:exec() and not **.sh and not **.py and not grep(r"^#!")'
