Switch time_t, ino_t, clock_t, and struct kevent's ident and data
members to 64bit types. Assign new syscall numbers for (almost
all) the syscalls that involve the affected types, including anything
with time_t, timeval, itimerval, timespec, rusage, dirent, stat,
or kevent arguments. Add a d_off member to struct dirent and replace
getdirentries() with getdents(), thus immensely simplifying and
accelerating telldir/seekdir. Build perl with -DBIG_TIME.

Bump the major on every single base library: the compat bits included
here are only good enough to make the transition; the T32 compat
option will be burned as soon as we've reached the new world are
are happy with the snapshots for all architectures.

DANGER: ABI incompatibility. Updating to this kernel requires extra
work or you won't be able to login: install a snapshot instead.

sched work by niklas and art backed out; causes panics

This patch is mortly art's work and was done *a year* ago. Art wants to thank
everyone for the prompt review and ok of this work ;-) Yeah, that includes me
too, or maybe especially me. I am sorry.

Change the sched_lock to a mutex. This fixes, among other things, the infamous
"telnet localhost &" problem. The real bug in that case was that the sched_lock
which is by design a non-recursive lock, was recursively acquired, and not
enough releases made us hold the lock in the idle loop, blocking scheduling
on the other processors. Some of the other processors would hold the biglock though,
which made it impossible for cpu 0 to enter the kernel... A nice deadlock.
Let me just say debugging this for days just to realize that it was all fixed
in an old diff noone ever ok'd was somewhat of an anti-climax.

This diff also changes splsched to be correct for all our architectures.

POSIX says rlim_t should be unsigned so make it u_quad_t. Also add
POSIX-mandated RLIM_SAVED_MAX and RLIM_SAVED_CUR defines. On OpenBSD
these are identical to RLIM_INFINITY as allowed by POSIX. OK

change arguments to suser. suser now takes the process, and a flags
argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root process. looks like
something i saw in freebsd, but a little different.
use of suser_ucred vs suser in file system code should be looked at again,
for the moment semantics remain unchanged.
