Rename sljitarch.h to sljit_machdep.h.

Add sljit support to arm.

branches: 1.9.8;
This change arm, armeb, earm, earmeb, earmhf, earmhfeb so all builds that
share a MACHINE_ARCH for userland so that except for etc, will produce
identical sets.

usr/include/machine now points to usr/include/arm

Don't install fp.h anymore

branches: 1.7.2; 1.7.12;
Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Remove arm support for IPKDB.

It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.

branches: 1.4.2; 1.4.8;
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: 1.3.2; 1.3.6;
Added support to detect AC adapter and charge battery.

branches: 1.2.4; 1.2.12; 1.2.14; 1.2.16;
+ mutex.h, rwlock.h

branches: 1.1.2; 1.1.4; 1.1.6; 1.1.8;
