header for the case where sizeof(time_t) != sizeof(int). dumprestore.h
was embedding time_t when it should have been embedding int32_t.
Use time_to_time32() and time32_to_time() to convert between the
protocoll/file-format time and time_t.
serve two purposes: (1) so we can maintain backwards compatibility with
protocols (rwhod, dump, etc...) that either assume time_t is 32 bits or
assume sizeof(time_t) == sizeof(int), or make other similar assumptions.
(2) To tag such routines (by the presence of these calls) for future
cleanup/extension work.
The 32->64 routine, time32_to_time() (when time_t is 64 bits, that is),
is defined specifically to implement temporal locality to properly set the
msb bits of a 64 bit time_t quantity, using the 50 year rule. The locality
code has not been implemented yet (and doesn't need to be for a while),
but that is the intent. This will allow us to maintain backwards protocol
compatibility past 2038.
These routines are intended to be platform and time_t agnostic.

Make it a panic to repeat make_dev() or destroy_dev(), this check
should maybe be neutered when -current goes -stable.
Whine if devsw() is called on anon dev_t's in a devfs system.
Make a hack to avoid our lazy-eval disk code triggering the above whine.

commit is preliminary to an attempt at cleaning it up.

coerces the deletion of a default ACL on a directory when no default
ACL EA is present to success. Because the UFS EA implementation doesn't
disinguish the EA failure modes "that EA name has not been
administratively enabled" from "that EA name has no defined data",
there's a potential conflict in error return values. Normally, the
lack of administratively configured EA support is coerced to
EOPNOTSUPP to indicate that ACLs are not available; in this case,
it is possible to get a successful return, even if ACLs are not
available because EA support for them has not been enabled.
Expand the comment in ufs_setacl() to identify this case.
