1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

2c37256e5a 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.

82dab6ce62 Make it possible to return more than one piece of control information
(PR #1178).
Define a new SO_TIMESTAMP socket option for datagram sockets to return
packet-arrival timestamps  as control information (PR #1179).

46f578e76a Fix for PR #1146: the "next" pointer must be cached before calling soabort
since the struct containing it may be freed.

be24e9e8fa Changed socket code to use 4.4BSD queue macros. This includes removing
the obsolete soqinsque and soqremque functions as well as collapsing
so_q0len and so_qlen into a single queue length of unaccepted connections.
Now the queue of unaccepted & complete connections is checked directly
for queued sockets. The new code should be functionally equivilent to
the old while being substantially faster - especially in cases where
large numbers of connections are often queued for accept (e.g. http).

dc915e7cfc Kill XNS.
While we're at it, fix socreate() to take a process argument.  (This
was supposed to get committed days ago...)

b135805469 Define a new socket option, SO_PRIVSTATE. Getting it returns the state
of the SS_PRIV flag in so_state; setting it always clears same.

ff5c09da20 Make somaxconn (maximum backlog in a listen(2) request) and sb_max
(maximum size of a socket buffer) tunable.

Permit callers of listen(2) to specify a negative backlog, which
is translated into somaxconn.  Previously, a negative backlog was
silently translated into 0.

9f518539fd Calling semantics for kmem_malloc() have been changed...and the third
argument is now more than just a single flag. (kern_malloc.c)
Used new M_KERNEL value for socket allocations that previous were
"M_NOWAIT". Note that this will change when we clean up the M_ namespace
mess.
