consistent with hostnames, don't allow whitespace in the program
name specifiers in syslog.conf either.

This allows boot to proceed on a real system until the issue
of calling back into certain OpenFirmware calls (e.g. finddevice)
in thread context is understood.

I changed version number back to 0) and will allow to merge this change

if we move to an NMI for stopping cpus instead, we can do away with this.

- Remove the sched_add wrapper that used sched_add_internal() as a backend.
Its only purpose was to interpret one flag and turn it into an int. Do
the right thing and interpret the flag in sched_add() instead.
- Pass the flag argument to sched_add() to kseq_runq_add() so that we can
get the SRQ_PREEMPT optimization too.
- Add a KEF_INTERNAL flag. If KEF_INTERNAL is set we don't adjust the SLOT
counts, otherwise the slot counts are adjusted as soon as we enter
sched_add() or sched_rem() rather than when the thread is actually placed
on the run queue. This greatly simplifies the handling of slots.
- Remove the explicit prevention of migration for ithreads on non-x86
platforms. This was never shown to have any real benefit.
- Remove the unused class argument to KSE_CAN_MIGRATE().
- Add ktr points for thread migration events.
- Fix a long standing bug on platforms which don't initialize the cpu
topology. The ksg_maxid variable was never correctly set on these
platforms which caused the long term load balancer to never inspect
more than the first group or processor.
- Fix another bug which prevented the long term load balancer from working
properly. If stathz != hz we can't expect sched_clock() to be called
on the exact tick count that we're anticipating.
- Rearrange sched_switch() a bit to reduce indentation levels.
and threads currently holding sleep mutexes (and spin mutexes for
curthread). This can be quite useful in looking for a lock condition
summary for a system, as it avoids manually iterating through threads
and processes to find all the interesting locks.
NB: "alllocks" is up there with "lockedvnods" for a bad argument for

lower the priority of the returning thread to a user priority before
calling into thread_userret() which would call wakeup() which in turn would
cause the returning thread to eventually context switch rather than
completing its slice. Allowing this thread to complete its slice first
yields a 15% performance improvement in super-smack on my dual opteron with
4BSD.

More work needs to happen here, as there's many conflicting vendor

problem is tackled.
This was inspired by recent discussions, but none of the patches
posted were consulted to produce this commit. Other, similar ones

as they are the setrunqueue() and sched_add() calls. Since they happen
immediately before the thread is placed on a run queue they would normally
dwarf the more informative preemption or yield event and it is implicitly
understood that a thread is back on the run queue as part of these events.
