50c2da8f27 Interrupt-driven, but slow, NCR 53c96 driver for the 040-based macs. Contains 
some guesses for the machines that have two of these buggers (I don't have
such a machine).  This driver is a copy of the sparc/alpha esp with a
minimum of changes--after we get it performing a bit more respectably,
we should see about re-normalizing the sources.

487a6bebfc Add a function to install an interrupt handler for 2nd scsi bus (Q900/950). 
Take a guess that it's at via2, bit 0 (where 5380 DRQ is).

6bb6fab4ce Changes from the hp300 trap.c: 
- Fix up usage of MBD_ISPID().  (from Jason Thorpe)
- Be careful not to deref bad pointers in the MMU fault handler.  (ditto)
- Ensure trap() never deals with a NULL proc, and if our proc has
  no pcb, punt.  (Suggested by Gordon Ross)

ccaecc2dda Some changes from hp300 (thanks Jason!): 
- Initialize proc0.p_addr just after setting up the kernel stack, to avoid
  getting NULL pointers in trap().  Change suggested by Gordon Ross.
- Panic if main() returns.

dca6a7e025 Critical fix from Bill Studenmund: if CTS is deasserted and then 
immediately reasserted before we get a chance to process the interrupt,
we can inadvertantly get stuck with zs_tx_stopped set.  Move the delta
detection to the hard zs interrupt handler; the softint handler
will notice that something has happened with CTS and restart the
transmitter if it's asserted.

f4eeb69eab Several 68040/68LC040-related changes; we're not there yet, but this 
brings us closer to basic operation.

  - Verified/updated ROM vector entries for many systems, and new vector
    table entries for LC 520, LC 575/577/578, and Quadra 950
  - Implement a new machine class (MACH_CLASSQ2) for the LC 575 series
  - Use the ptest040() helper function in get_physical().

Also, in straytrap(), only enter the debugger #ifdef DDB.
