* add "MIPS_3k_" for the MIPS-I r[23]000-specific register definitions.
* add "MIPS_4k_" for the MIPS-II/III r4000-specific register definitions.
* add #defines that provide the old values for locore and user
code, so the existing code continues to compile.
Regression-tested against the old headers by grepping for #define's,
editing out the defined symbols, and preprocessing with both the previous
machConst.h headers and this version.
Some unused symbols (CPU and FPU must-be-zero constants) are no longer defined.
Pica interrupt masks are now constant expressions instead of constant
values.
TODO:
* factor out the common #defines into src/sys/arch/mips.
* Get rid of the Sprite coding-style names (MACH_xxx).
* Separate out the r3k/r4k differences from the Pica/pmax differences.
* Figure out how to have a run-time choice of r3k vs. r4k support,
instead of a compile-time choice.

A merged version with the NetBSD/pmax revision history is in mips/mips/.

* Delete pmax-specific functions and declarations from trap.c
* Delete mips-geeneric functions and declaratinos from pmax_trap.c
* Rename the function pointer used to handle hardware interrupts to
"mips_hardware_intr". Define it in trap.c. Change references elsewhere,
including machdep.c.
Verified to boot on a 5000/200.
* Add spl4() and spl5() functions from the Pica port.
* Add MachFPTrap() as an alternate entry point for MachFPInterrupt.
The r4k reports floating-point execptions as a trap, not an interrupt,
and the Pica port uses the name MachFPTrap().
* Add nops to the Mach_spl?() functions and MachFPInterrupt, as required
for the r4k port.

Copy the kn02 memory-interrupt reporting function to the kn03 (5k/240)
memory-error handler, since the 3MAXPLUS seems to use the same ECC hardware
as the 3MAX.

pica tree are changed to use <mips/asm.h> directly, just do
#include <mips/asm.h>, for compatibility.
opcodes from the Pica port. Per Fogelstrom claims the latter are all
supposedly MIPS-II (r6000) instructions, rather than MIPS-III (R4000),
but we haven't checked to be sure. Are LL/SC really in MIPS-II?

code following the MIPS ELF abi.
* Move the kn01 interrupt handler outside of #ifdef DS5000, to support
3100-only kernels.
* Add #ifdef DS3100 around kn01_enable_intr() to allow configuring
turbochannel-only kernels.
Configuration-time support for specific models of DECstation still needs
more thought/work.

the NetBSD-1.1 convention. Change the mainbus `struct confargs'
and the "generic" interrupt-establish method, used by devices that
appear on both a kn01 and TC decstations, to match.
Change the macros in autconf.h accordingly.
Add new device-attach struct cfattach le_tc_ca and struct cfdriver le_cd.
Change IOASIC cfdriver references from "ioasiccd" to "ioasic_cd".
Change "mainbuscd" to "mainbus_cd"
update the old-config to new-config glue used with the 4.4bsd/pmax
SCSI drivers to use new device attach declarations and names for
the "oldscsibus", "tz" and "rz" drivers.
- split softc size and match/attach out from cfdriver into

A name change is necessary to avoid a name clash with sys/dev/tc/tc.c,
which also creates a tc.o.
