SC_DEV isn't NULL; if it is, evaluate to NULL and don't dereference
NULL. Callers of VIRTUAL_TTY must already check for the result being
NULL since si_tty can be NULL, so this should be safe.
This fixes a panic when trying to switch to a different vty in an
environment such as userconfig (-c option to the kernel).

the saved uid and gid during execve(). Unfortunately, the optimizations
were incorrect in the case where the credential was updated, skipping
the setting of the saved uid and gid when new credentials were generated.
This change corrects that problem by handling the newcred!=NULL case
correctly.

This problem only exists in -CURRENT. Most often it is reproduced when
compiling some perl extension manually. Make test uses PERL_DL_NONLAZY,
and if a tested module uses POSIX, boom!
Luckily, we don't see it very often, mostly because the vast majority of
p5 ports do not perform the `make test' step.

The patch I used isn't quite the one Lars suggested, but the size
of the largest datagram you can recv isn't #defined anywhere, and
probably isn't even bounded for some protocols.

for authentication to PAM. This meens that WHEELSU-type logic can
now be effected in the pam.conf "su" configuration stack. While here,
clean up the mess that the code had assumed over years of hacking by
folks using different styles. ANSIfy.
There is more policy in here that can be handed over to PAM. This will
be revisited.
despite the fact that most people want to set exactly the same settings
regardless of which card they have. It has been repeatidly suggested
that this configuration should be done via ifconfig. This patch
implements the required functionality in ifconfig and add support to the
wi and an drivers. It also provides partial, untested support for the
awi driver.

dev_t. The dev_depends(dev_t, dev_t) function is for tying them
to each other.
When destroy_dev() is called on a dev_t, all dev_t's depending
on it will also be destroyed (depth first order).
Rewrite the make_dev_alias() to use this dependency facility.
kern/subr_disk.c:
Make the disk mini-layer use dependencies to make sure all
relevant dev_t's are removed when the disk disappears.
Make the disk mini-layer precreate some magic sub devices
which the disk/slice/label code expects to be there.
kern/subr_disklabel.c:
Remove some now unneeded variables.
kern/subr_diskmbr.c:
Remove some ancient, commented out code.
kern/subr_diskslice.c:
Minor cleanup. Use name from dev_t instead of dsname()
In the past 2 months or so, after rlogining into another host, the
environment has the geometry wrong. Peter suggested that this behavior
change was most likely caused by the PAM stuff that changed to run a proper
session with a forked child. And that for some reason the window size is
no longer being transferred via an OOB message on the socket.
This change fixes my problem and seems to be a good stopgap measure until
someone has time to ktrace/ktrace -i inetd to catch all the child processes
it spawns while doing an rlogin and change window size a few times to see
how far the change messages are getting.
