Add NWS-4000 support.

Based on nonaka@'s porting effort back in 2002.
See announcement on port-newsmips@ for more details:

branches: 1.13.54; 1.13.56;
Merge forward matt-nb5-mips64
Adapt to new interrupt/spl framework

branches: 1.12.22; 1.12.26; 1.12.32; 1.12.34;
Split device_t/softc, with misc cleanup.

branches: 1.11.16;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

branches: 1.10.10;
- add a declaration of apbus_wbflush() in apbusvar.h
- include <mips/locore.h> for mips3_wbflush()
- undef wbflush() macro before declaration of local inlined wbflush()

branches: 1.9.2; 1.9.4; 1.9.10;
Cast to char* before doing pointer arithmetic.
Also put * close to variable name.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.7.26;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

merge ktrace-lwp.

branches: 1.5.6;
Misc cleanup:
- ANSI function decls
- remove __P()
- u_intNN_t -> uintNN_t
- remove register decls
- bcopy -> memcpy, strcpy
- bzero -> memset
- bcmp -> memcmp
- use malloc(9) with M_ZERO
- some KNF
etc.

branches: 1.4.8; 1.4.10;
Declare sc_regbase as volatile, so that if_sn.c works with gcc3.

XXX We should switch to MI SONIC driver.

branches: 1.3.24;
Make this stuff compile with -wstrict-prototpes -wmissing-prototypes.
More use of prototypes inside includes should be done.

branches: 1.2.2;
change the type of the apbus interrupt handler from void to int
for each driver to indicate the interrupt has been handled or not.

First cut of news5000 support.
Mostly from SHIMIZU Ryo <dejiko@di.gi.charat.org>.
