default to apple layout for both adb and usb keyboards

make us.apple the default USB keyboard layout

set options ADBKBD_EMUL_USB by default
With this ADB and USB keyboards can coexist on the same mux, as needed by
built-in Bluetooth modules on some *Books

Import config(9) file and register HAL's files in the build machinery.

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.

1st cut of Powermac G5 support (uses bridge mode).

Rename AH_DEBUG, AH_ASSERT, and AH_DEBUG_ALQ to ATH_XXX.
Use the opt_ah.h for the provided HAL to get options like AH_REGOPS_FUNC.
Add AH_REGOPS_FUNC to a few opt_ah.h that don't have it in this version
of the HAL but need it. (The next version from Sam should have this fixed
in it. If it doesn't, then we'll have to take care at import time.)

Ultimately, this should make future imports even easier, and individual ports
should not have to worry about whether AH_REGOPS_FUNC is properly defined or
not, since the opt_ah.h will just take care of it automatically.

Ok'd by dyoung@.

branches: 1.19.4; 1.19.6; 1.19.8; 1.19.10; 1.19.12;
merge ktrace-lwp.

Define AH_REGOPS_FUNC because the macppc HAL uses the register
read/write functions to access the hardware.

branches: 1.17.2;
include "conf/std".

branches: 1.16.16;
Remove SPILLSTK leftovers.

branches: 1.15.2;
Rename PPC_MPC6XX to PPC_OEA (and any mpc6xx reference to oea).

Perform a rototill of the powerpc code. Mandate use of SPRG0 to store
a pointer to current cpu's cpu_info structure. Use cpu_info for
intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on
non-MULTIPROCESSOR machines. Add common macros GET_CPUINFO and
INIT_CPUINFO to get and initialize the cpu_info struct on startup. Make
ibm4xx use the standard <powerpc/frame.h>. Use IFRAME_xx in ibm4xx
trap_subr.S instead of explicit magic offsets. Move INTSTK and SPILLSTK
to std.<platform>. Change faultbuf to a struct instead of an array.

On MPC6XX cpus, stop using the vector page for temporary space and use
reserved space in cpu_info.

Use a common genassym.cf for all the PPC_MPC6XX ports. Add a makeoptions to
std.foo to indicate the directory to get genassym.cf from. Add an intrframe
to <powerpc/frame.h> and make trap_subr.S use symbolic offsets into it.

branches: 1.12.2; 1.12.8;
Change comment.

Changes new pmap, common param.h, vmparam.h, and moved includes.

branches: 1.10.2;
For now, all macppc will get OpenPIC

Remove prefix construction for softdeps. Add SOFTDEP option to GENERIC.

branches: 1.8.4;
Add

prefix ../gnu/sys
cinclude "conf/files.softdep"
prefix

to all std.* files, so that soft dependencies can be activated using
"options SOFTDEP".

branches: 1.7.2; 1.7.8;
eliminate the PMAP_NEW option by making it required for all ports.
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.

clean up kernel/config files files for machVM lossage.

Remove bogus comment.

Switch to UVM on macppc.

Remove HTABENTS definition. (calculated automatically)

fic typi

Use a std options file, like other ports do.
