Modify the kernel to use the new pr_usrreqs interface rather than the old
pr_usrreq mechanism which was poorly designed and error-prone. This
commit renames pr_usrreq to pr_ousrreq so that old code which depended on it
would break in an obvious manner. This commit also implements the new
interface for TCP, although the old function is left as an example
(#ifdef'ed out). This commit ALSO fixes a longstanding bug in the
TCP timer processing (introduced by davidg on 1995/04/12) which caused
timer processing on a TCB to always stop after a single timer had
expired (because it misinterpreted the return value from tcp_usrreq()
to indicate that the TCB had been deleted). Finally, some code
related to polling has been deleted from if.c because it is not
relevant t -current and doesn't look at all like my current code.

Move or add #include <queue.h> in preparation for upcoming struct socket
changes.

Removed unnecessary #includes of vm stuff. Most of them were once
prerequisites for <sys/sysctl.h>.

subr_prof.c:
Also replaced #include of <sys/user.h> by #include of <sys/resourcevar.h>.

New style sysctl & staticize alot of stuff.

Start adding new style sysctl here too.

Fix a logical error in T/TCP: when we actively open a connection, we
have to decide whether to send a CC or CCnew option in our SYN segment
depending on the contents of our TAO cache. This decision has to be
made once when the connection starts. The earlier code delayed this
decision until the segment was assembled in tcp_output() and
retransmitted SYN segments could have different CC options.
