thorpej f8ae3272b9 Back out previous soqinsque() and soqremque() changes. This will
stop the panics until the socket queues get converted to <sys/queue.h>.

thorpej 26a25a87b2 Optimization of soqinsque() and soqremque():
Keep queue of pending sockets in a double linked list.  Previously,
a singly linked list was used, giving O(N) insertion/deletion times,
and was a major time consumer for sockets with large pending queues.
The double linked list give O(C) insertion/deletion times with only
a small cost in complexity.

Since a socket can be on, at most, one queue at a time, both so_q and
so_q0 can safely be used as (forward and backward, respectively) queue
pointers.

Submitted my Matt Thomas <matt@3am-software.com>, a long time ago.
(Geez, I've been running with this patch for _months_, and had completely
forgotten about it!)

mycroft 49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.
Remove SS_PRIV completely.
