add a signal to a mailbox's pending set.
- Add a new function, thread_signal_upcall(), this causes the current thread
to upcall so that we can deliver pending signals.

I should have listenned to the other mind.

seed->first value correlation. It breaks rand_r()... Other possible methods
like shuffling inside aray will breaks rand_r() too, because it assumes
only one word state, i.e. nothing extra can be added after seed assignment
in srand().
BTW, for old formulae seed->first value correlation is not so monotonically
increased as with other Linear Congruential Generators of this type only
becase arithmetic overflow happens. But overflow affects distribution
and lower bits very badly, as many articles says, such type of overflow
not improves PRNG.
So, monotonically increased seed->first value correlation problem remains...
The problem with the previous attempt, as noticed by Marcel, was that
stacknxt was being aligned to a pointer boundary instead of an
ALIGNBYTES + 1 boundary, which broke sparc64.
Wearing said pointy hat, correct the oversight and hope nobody
notices.

Also unwrap some not-so-long lines.

queue lock already held.
- In getblk() and flushbufqueues() use bremfreel() while we still have the
buf queue lock held to keep the lists consistent.
- Add LK_NOWAIT to two cases where we're essentially asserting that the bufs
are not locked while acquiring the locks. This will make sure that we get
the appropriate panic() and not another one for sleeping with a lock held.
These variables will be used by pkg_add, which installs mkisofs package
while MAKE_ISOS=YES. See src/release/${arch}/mkisoimages.sh if you doubt.

using the alignment from sys/param.h (16) instead of the alignment
from machdep.h (8) tickled a nasty bug in the memory allocator that I
haven't been able to track down yet.
