Pavel Emelyanov 3f602d2724 userfaultfd: Rename uffd_api.bits into .features 
This is (seems to be) the minimal thing that is required to unblock
standard uffd usage from the non-cooperative one.  Now more bits can be
added to the features field indicating e.g.  UFFD_FEATURE_FORK and others
needed for the latter use-case.
