baddaf9480 Switch 586/686 back to generic_bzero and #if 0'd the "optimized" code. It 
turns out that it actually reduces performance in real-world cases.

c80faa792c Work around a braindead signal handling in many newer HP printers. 
They don't have BUSY de-asserted by the time they ACK (and thus cause
an interrupt).  The workaround is to try seeing if the BUSY will be
de-asserted soon, and if not, to use an incremental backoff and
semi-polled mode instead of the fixed timeout with 1/2 s we've been
using previously (that caused the printer to run really slooow).

Printers that have been working previously should not be affected by
this.

030ad08012 Fixed a problem that the UPAGES of a process were being run down 
in a suboptimal manner.  I had also noticed some panics that appeared
to be at least superficially caused by this problem.  Also, included
are some minor mods to support more general handling of page table page
faulting.  More details in a future commit.

ef9805a3c8 Moved rtcin() to clock.c. 
Always delay using one inb(0x84) after each i/o in rtcin() - don't
do this conditional on the bogus option DUMMY_NOPS not being defined.
If you want an optionally slightly faster rtcin() again, then inline
it and use a better named option or sysctl variable.  It only needs
to be fast in rtcintr().

6e9d1d8bb6 Fix support for the aic7850 by looking only at the relavent bits of the 
QINCNT.  The 7850 puts random garbage in the high bits and all my attempts
to determine the cause of this failed.  This approach does seem to work
around the problem.

Go back to relying on the SCSIPERR interrupt instead of having the sequencer
interrupt at the beginning of ITloop after a parity error occured.

Determine the number of SCBs on a card automatically and base the qcntmask
on the number of SCBs.

Add entries for 11.4MHz, 8.8MHz, 8.0MHz, and 7.2MHz to ULTRA portion of
the syncrate table.  They seem to work fine on the 2940UW I have here and
will allow more non-ultra devices (like my tape drive) to run sync while
the adapter is in ULTRA mode.

Return XS_SELTIMEOUT instead of XS_TIMEOUT for selection timeouts.  I was
getting sick of waiting for the SCSI code to retry each non-existant unit
multiple times during boot and XS_SELTIMEOUT bypasses all retries.

Use new SLIST queue macros.  This was inspired by NetBSD using TAILQs in
their SCSI drivers.  For optimum cache hits, the free scb list should
be LIFO which is what the old and new code does.  NetBSD implemented a
FIFO queue for some reason.

Spaces -> tabs.

8dec8ed218 Nit: according to the Harvard code, it is necessary to clear the timestamp 
counter before loading the performance-monitor control register.  I'm
not sure I believe this, but we'll follow their lead for the moment.

I wrote now works (the program will find its way to share/examples).
