Reserve a mount flag, MNT_MULTILABEL, used by the MAC subsystem and
individual filesystems to determine whether they should operate in
"file system as a single object" mode, or "file system as a set of objects
with individual labels" mode. Note: in the trustedbsd_mac branch,
this is refered to as "MNT_MULTILEVEL", but the two mean the same thing.
MNT_MULTILABEL is more suggestive of a flexible policy system than one
providing purely hierarchal policies. The need for a reserved flag will
go away once nmount() is done.
