Previously we had to include <machine/param.h> or <sys/param.h> bogusly
due to the fact that <sys/socket.h> CMSG macros needed the ALIGN macro,
which was defined in param.h. However, including param.h was a disaster
for namespace pollution.
This solution, as contributed by shin a while ago, fixes it elegantly
by wrapping the definitions around some namespace pollution preventer
definitions.
This patch was long overdue.
This should allow any network programmer to use <sys/socket.h> as
before.

argument. These flags include INTR_FAST, INTR_MPSAFE, etc.
- Properly handle INTR_EXCL when it is passed in to allow an interrupt
handler to claim exclusive ownership of an interrupt thread.
- Add support for psuedo-fast interrupts on the alpha. For fast interrupts,
we don't allocate an interrupt thread; instead, during dispatching of an
interrupt, we run the handler directly instead of scheduling the thread
to run. Note that the handler is currently run without Giant and must be
MP safe. The only fast handler currently is for the sio driver.

because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.
Define __offsetof() in <machine/ansi.h>
Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>
Remove myriad of local offsetof() definitions.
Remove includes of <stddef.h> in kernel code.
NB: Kernelcode should *never* include from /usr/include !
Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.
Deprecate <struct.h> with a warning. The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

change_ruid() in kern_prot.c. This fixes an incorrect use
of chgproccnt().
Update both osf1_setuid() and osf1_setgid() to use setsugid() instead
of just frobbing the flag.

type of software interrupt. Roughly, what used to be a bit in spending
now maps to a swi thread. Each thread can have multiple handlers, just
like a hardware interrupt thread.
- Instead of using a bitmask of pending interrupts, we schedule the specific
software interrupt thread to run, so spending, NSWI, and the shandlers
array are no longer needed. We can now have an arbitrary number of
software interrupt threads. When you register a software interrupt
thread via sinthand_add(), you get back a struct intrhand that you pass
to sched_swi() when you wish to schedule your swi thread to run.
- Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit
more intuitive. Also, prefix all the members of struct intrhand with
'ih_'.
- Make swi_net() a MI function since there is now no point in it being
MD.

more include file including <sys/proc.h>, but there still is this wonky
and (causes warnings on i386) reference in globals.h.
CURTHD is now defined in <machine/globals.h> as well. The correct thing
to do is provide a platform function for this.
