84d4f509f0 Major speedup to /dev/random and the kernel thread that reseeds it. 
There is no more TAILQ fifo to harvest the entropy; instead, there
is a circular buffer of constant size (changeable by macro) that
pretty dramatically improves the speed and fixes potential slowdowns-
by-locking.

Also gone are a slew of malloc(9) and free(9) calls; all harvesting
buffers are static.

All-in-all, this is a good performance improvement.

Thanks-to:	msmith for the circular buffer concept-code.

81babfd043 Make the Not RESPONSE in RESPONSE QUEUE message have a bit more info 
(specifically, how many entries we've looked at so far). Maintain
interrupt instrumentation. Use USEC_SLEEP instead of USEC_DELAY in
a number of places (this allows us to drop locks and sleep instead
of spin). Track changes to configuration options for topology preference.
Fix botched order of printout for Channel, Target, Lun.

67afe757a2 Add interrupt instrumentation. Change ISP_CFG_NPORT config option to 
a set of options that allows specific loop, loop-only, nport, nport-only
topology settings. Define a required macro for all platforms (USEC_SLEEP).

4cb1e53914 Recouple arc4random(9) to the entropy device. This works whether the 
entropy device is loaded or not.

If the entropy device is NOT loaded, the the quality of perturbations
supplied by this will suffer.

86360fee54 Remove thr_sleep and thr_wakeup. Remove fields p_nthread and p_wakeup 
from struct proc, which are now unused (p_nthread already was).
Remove process flag P_KTHREADP which was untested and only set
in vfs_aio.c (it should use kthread_create).  Move the yield
system call to kern_synch.c as kern_threads.c has been removed
completely.

b852b893a3 introduce support for static compilation of the osf/1 module via the

6e4708aa12 exec_osf1_imgact() should return -1 for non OSF1/ECOFF binaries, it should 
not return ENOEXEC.  This is because image activators should return -1 if they
don't claim an image. They should return ENOEXEC if they do claim it,
but cannot load it due to sime problem with the image.   This bug was
preventing static compilation of the osf/1 module.  I'm surprised it
did not cause more problems.

794cd879fe Make sure to free the sf_buf if we've allocated it but fail to allocate 
an mbuf (ENOBUFS) before returning so that we don't leak sf_bufs in
the case where we're out of mbufs.

bbe8edb0ac Fix some error-handling logic so that ferror is called before fclose, 
instead of immediately after the fclose.  The previous logic did work
on freebsd, but is somewhat risky practice (and causes trouble when
porting to other OS's).

6e01adb67f Alter isa interrupt behaviour on alpha. Rather than send a non-specific 
EOI after the ithread runs, send the EOI when we get the interrupt and
disable the source.  After the ithread is run, the source is renabled.
Also, add isa_handle_fast_intr() which handles fast interrupts by sending
an EOI after the handler is run.

This fixes the chronic missing interrupt problems under heavy NFS load
on my UP1000 and should result in greater stability for alphas which
route all irqs through an isa pic.

Discussed with: jhb, bde (sending non-specific EOIs early was bde's idea)

689634a3ea Convert the pcib_{read,write}_config args from signed to unsigned, 
like the args to the config space accessors these functions replaced.

This reduces the likelyhood of overflow when the args are used in
macros on the alpha.  This prevents memory management faults when
probing the pci bus on sables, multias and nonames.
