Rework the way kernel include files are installed. In the new method,
...
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Fix for ADB hang while probing, based on information from Colin Wood:
...
Rather than waiting indefinitely for a mouse or extended keyboard to
respond -- which may not even exist -- time out after 2 seconds and
continue. This corrects a very common problem with the MRG-based ADB
driver that has bitten many people running 1.3.

Fix a bogosity apparently inherited from when the Utah 4.3BSD code base
...
was converted to use Mach VM for Net2/4.4BSD. The user segment table
pointer was originally stored in the PCB. When Mach VM came along,
however, it was also stored in the pmap, and loaded into the PCB in
pmap_activate(). pmap_activate() would then note that the PCB's USTP
was now in sync with the pmap's USTP, and the low-level context switch
code would use the value from the PCB.
However, pmap_activate() would also load the hardware MMU context if
the pmap was the current pmap (or, in the case where pmaps can be shared,
such as in NetBSD, if the proc was the current proc). The low-level
context switch code would then reload the hardware _again_ using the
USTP from the PCB.
However, the optimization of not calling pmap_activate() if "stchanged"
was false ended up causing some processes to use stale USTP values from
the PCB when the low-level context switch code reloaded the hardware!
This was noticed by using a real vfork(2) (which worked for some time
before failing, surprisingly!)
Since I'm hard pressed to find any real optimization here (since the
hardware was always reloaded once, sometimes twice!), the code now always
calls pmap_activate(), which uses the correct USTP value (the one in the
pmap). The PCB's USTP is now ignored, and should eventually be g/c'd.
Another optimization can actually be performed, and I have added a comment
describing what it is, but have not yet implemented it.
Also note that most of the loadustp() functions where actually incomplete.
This has been corrected. These functions should probably be split up into
MMU-specific operations, and called indirectly, rather than doing constant
run-time decision making based on values that will never change during the
course of a boot's lifetime.

PR 4078: Enabling the SCSI IRQ interrupt to allow reselects to work
...
causes the MI interrupt handler to barf when we get a 5380 RST interrupt
while probing. Worse, the VIA latches the interrupt, so simply having
all interrupts disabled during autoconfig doesn't resolve the problem.
[I demonstrated the latter on a IIci, which erroneously reports a
reselection attempt(!) after autoconfig is complete. The latched
interrupt results from the SCSI bus reset we do when initializing the
bus.]
Since interrupts must be enabled during autoconfig anyway (sigh), test
to see if autoconfig has completed in sbc_irq_intr(). If not, we don't
pass the interrupt up to the MI interrupt handler. Also, make sure to
clear the VIA interrupt if we're servicing an unclaimed 5380 RST
interrupt.
Thanks to Bill Studenmund for providing the key insight needed to unlock
this problem.
