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.

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

ANSIify. Use uint<N>_t. Drop unnecessary includes.
Drop trailing whitespace.

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

__HAVE_NWSCONS seems to mean, "If this port uses pckbc(4), it also uses
sys/dev/pckbc/files.pckbc." This is true of sparc, so define __HAVE_NWSCONS,
and remove the code in pckbc_machdep_cnattach() that was conditional on its
not being defined and that is no longer needed (since with __HAVE_NWSCONS,
pckbc_cnattach() will call pckbd_cnattach() itself if necessary).

Use the new split hard/softinterrupt handlers to avoid running mouse/keyboard
input functions to be run at IPL_SERIAL (instead of the intended IPL_TTY).

__KERNEL_RCSID()

Remove the `flags' argument from bus_intr_establish().

Search children of the "8042" node to check if keyboard is the stdin.

Add trailing ; to CFATTACH_DECL.

Use CFATTACH_DECL().

Declare all cfattach structures const.

Switch to shared EBus headers in dev/ebus.
