lookup vop so that it defaulted to using vop_eopnotsupp for strange
lookups like the ones for open("/dev/null/", ...) and stat("/dev/null/",
...). This mainly caused the wrong errno to be returned by vfs syscalls
(EOPNOTSUPP is not in POSIX, and is not documented in connection with
specfs in open.2 and is not documented in stat.2 at all). Also, lookup
vops are apparently required to set *ap->a_vpp to NULL on error, but
vop_eopnotsupp is too broken to do this.
current_file_name and current_link_name sometimes point into the
middle of malloc()ed memory and sometimes point to alloca()ed memory,
but free() is sometimes called on them. This seems to be harmless
for the usual tar operations, but it is usually fatal for `tar -W'.
E.g., for `cd /etc; tar Wcf /tmp/foo rc', at the start of
verify_volume(), current_file_name points to alloca()ed memory, and
tar attempts to free it.

register our sub-busses in the reversed order. In the future, we may provide
a hint to CAM on how to order the scans for multi-function adapters that also
set this flag, but trying to do it the "twin channel" way will lead to
a panic.

In the SEE ALSO section, -mdoc automatically emits an empty line

o Back out the __std* stuff. Can't figure out how to do this right now,
so we'll save it for late.
o use _up as a pointer for extra fields that we need to access.
o back out the libc major version bump.
