When a prison is given the ability to create raw sockets (when the
security.jail.allow_raw_sockets sysctl MIB is set to 1) where privileged
access to jails is given out, it is possible for prison root to manipulate
various network parameters which effect the host environment. This commit
plugs a number of security holes associated with the use of raw sockets
and prisons.

This commit makes the following changes:

- Add a comment to rtioctl warning developers that if they add
  any ioctl commands, they should use super-user checks where necessary,
  as it is possible for PRISON root to make it this far in execution.
- Add super-user checks for the execution of the SIOCGETVIFCNT
  and SIOCGETSGCNT IP multicast ioctl commands.
- Add a super-user check to rip_ctloutput(). If the calling cred
  is PRISON root, make sure the socket option name is IP_HDRINCL,
  otherwise deny the request.

Although this patch corrects a number of security problems associated
with raw sockets and prisons, the warning in jail(8) should still
apply, and by default we should keep the default value of
security.jail.allow_raw_sockets MIB to 0 (or disabled) until
we are certain that we have tracked down all the problems.

Looking forward, we will probably want to eliminate the
references to curthread.

This may be a MFC candidate for RELENG_5.

Make the interrupt FAST & MPSAFE since it is just a simple

Rely on a per controller mutex to protect the bioqueues.
Grab GEOMs topology lock when we have to and Giant when
ISADMA needs it.  Since all access to the hardware is
isolated in the per controller thread, the rest of the
driver is lock & Giant free.

Create a per-drive queue where requests are parked while
the motor spins up.  When the motor is running the requests
are purged to the per controller queue.  This allows
requests to other drives to be serviced during spin-up.

Only setup the motor-off timeout when we finish the last
request on the queue and cancel it when a new request
arrives.  This fixes the bug in the old code where the motor
turned off while we were still retrying a request.

Make the "drive-change" work reliably.  Probe the drive on
first opens.  Probe with a recal and a seek to cyl=1 to
reset the drive change line and check again to see if we
have a media.

When we see the media disappear we destroy the geom provider,
create a new one, and flag that autodetection should happen

  Specifically, if a thread is awakened by something other than a signal
  while checking for signals before going to sleep, clear TDF_SINTR in
  sleepq_catch_signals().  This removes a sched_lock lock/unlock combo in
