Fix a long standing race between sleep queue and thread
suspension code. When a thread A is going to sleep, it calls
sleepq_catch_signals() to detect any pending signals or thread
suspension request, if nothing happens, it returns without
holding process lock or scheduler lock, this opens a race
window which allows thread B to come in and do process
suspension work, however since A is still at running state,
thread B can do nothing to A, thread A continues, and puts
itself into actually sleeping state, but B has never seen it,
and it sits there forever until B is woken up by other threads
sometimes later(this can be very long delay or never
happen). Fix this bug by forcing sleepq_catch_signals to
return with scheduler lock held.
Fix sleepq_abort() by passing it an interrupted code, previously,
it worked as wakeup_one(), and the interruption can not be
identified correctly by sleep queue code when the sleeping
thread is resumed.
Let thread_suspend_check() returns EINTR or ERESTART, so sleep
queue no longer has to use SIGSTOP as a hack to build a return
value.

When the VM needs to allocated physical memory pages (for non interrupt use)
and it has not plenty of free pages it tries to free pages in the cache queue.
Unfortunately freeing a cached page requires the locking of the object that
owns the page. However in the context of allocating pages we may not be able
to lock the object and thus can only TRY to lock the object. If the locking try
fails the cache page can not be freed and is activated to move it out of the way
so that we may try to free other cache pages.
If all pages in the cache belong to objects that are currently locked the
cache queue can be emptied without freeing a single page. This scenario caused
two problems:
1) vm_page_alloc always failed allocation when it tried freeing pages from
the cache queue and failed to do so. However if there are more than
cnt.v_interrupt_free_min pages on the free list it should return pages
when requested with priority VM_ALLOC_SYSTEM. Failure to do so can cause
resource exhaustion deadlocks.
2) Threads than need to allocate pages spend a lot of time cleaning up the
page queue without really getting anything done while the pagedaemon
needs to work overtime to refill the cache.

Move the "r p d s w" fields to the left to create space for expansion.
3 columns were wasted at the left, except these columns were used to
make the header line up. Now there is no space on the same line for
the "Proc:" part of the header. Try putting this on the line above
although it clutters that line (there is already similar clutter for
the "Interrupts" header). Leave 1 column between these fields. With
the above and a previous change there is enough of space for this.
Use 5 columns instead of 3 for the number of users since 3 is not quite
enough and there was space to spare. This also fixes an off-by-2 error
in a previous fix forthe column count in the comment on STATROW.

Reduce the field width by 1 for many numeric fields so that most fields
cannot run into other fields or field descriptors. If the value is
too large to fit in the field width, then the output format is adjusted
so that the value (usually) fits, but with fields running together
externally this adjustment usually didn't help. Mostly it doesn't
matter to lose 1 digit of precision, but switching the output format
is bad if it happens often or gives bogus units. The loss of width
is most serious for fields near "Csw" (which are also the ones which
must often ran together) since these have a high variance and large
values relative to the possible field widths so the switch occurs more
often now, and for the memory size fields where the switch gives the
bogus units kKB or MKB.
Now only the fields for r, p, d, s and w can run into each other.
These fields have width 3, and 3 cannot be reduced to 2 without losing
all precision when the value is between 100 and 999.
Trim "pdwake" to "pdwak" at think time now that it doesn't get clobbered
at runtime. The manpage doesn't need to be changed for this because
it documents the clobbered descriptor, unlike for 4 other too-long
descriptors which only get clobbered if there are lots of interrupt
sources.
Trim "% busy" to "%busy" since most other descriptors for percentages
are spelled without the space and this change makes changing the widths
of the %busy fields unnecessary.
