o Add typedefs for gid_t, off_t, pid_t, and uid_t in the non-standards
case.
o Add struct iovec (also defined in <sys/uio.h>).
o Add visibility conditionals to avoid defining non-standard
extentions in the standards case.
o Change spelling of some types so they work without including
<sys/types.h> (u_char -> unsigned char, u_short -> unsigned short,
int64 -> __int64, caddr_t -> char *)
o Add comments about missing restrict type-qualifiers and missing
function.
- Begin moving scheduler specific functionality into sched_4bsd.c
- Replace direct manipulation of scheduler data with hooks provided by the
new api.
- Remove KSE specific state modifications and single runq assumptions from
kern_switch.c

the locking of the proc lock after the goto to done1 to avoid locking
the lock in an error case just so we can turn around and unlock it.
- Move the exec_setregs() stuff out from under the proc lock and after
the p_args stuff. This allows exec_setregs() to be able to sleep or
write things out to userland, etc. which ia64 does.

So do GEOM. Not a pretty sight.
Take all the interesting stuff out of GEOM::disk_create(), and leave just
the creation of the fake dev_t. Schedule the topology munging to happen
in the g_event thread with g_call_me().
This makes disk_create() pretty lock-agnostic, almost lock-atheist.

This doesn't necessarily make bge(4) now actually *work* on an alpha.
It loads, configures, and then about 30 seconds later, my XP1000 hard
freezes. But, hey, it's a start.

One bug fixed: Use getmicrouptime() to trigger reseeds so that we
cannot be tricked by a clock being stepped backwards.
Express parameters in natural units and with natural names.
Don't use struct timeval more than we need to.
Various stylistic and readability polishing.
Introduce arc4rand(void *ptr, u_int len, int reseed) function which
returns a stream of pseudo-random bytes, observing the automatic
reseed criteria as well as allowing forced reseeds.
Rewrite arc4random() in terms of arc4rand().

- add wrappers for mmap2(2) and ftruncate64(2) system calls;
- don't spam console with printf's when VFAT_READDIR_BOTH ioctl(2) is invoked;
- add support for SOUND_MIXER_READ_STEREODEVS ioctl(2);
- make msgctl(IPC_STAT) and IPC_SET actually working by converting from
BSD msqid_ds to Linux and vice versa;
- properly return EINVAL if semget(2) is called with nsems being negative.

vcanrecycle to check a free vnode's availability. If it is
available, vcanrecycle returns an error code of zero and the
vnode in question locked. The getnewvnode routine then used
to call vn_start_write with the V_NOWAIT flag. If the filesystem
was suspended while taking a snapshot, the vn_start_write would
fail but getnewvnode would fail to unlock the vnode, instead
leaving it locked on the freelist. The result would be that the
vnode would be locked forever and would eventually hang the
system with a race to the root when it was attempted to recycle
it. This fix moves the vn_start_write check into vcanrecycle
where it will properly unlock the vnode if it is unavailable
for recycling due to filesystem suspension.
