Preliminary fixes for KASLR support.

The kernel pmap is guaranteed to always be valid for the identity region.

[IOKit]
- Remove "md0" hack for ARMPBA8. Not needed anymore.
[OSFMK]
- Redid Debugger() logic again, much simpler and no long thread backtraces. Panics look
very similar to i386 again.
- Video console misc changes (changing time for acquire for spinnywheel).
- Show kext suballoc region no matter what.
- Traps now have much nicer user messages for kernel fatal ones.
[PEXPERT]
- RealView now will use 32-bit display.
- Add option to OMAP3530 to not mess with the framebuffer/DSS settings.
- Syntax changes. No functional change otherwise.

Linux-printk style timing.

Preliminary support for UNIX signals.

Make the spinner white.

New 'Halt_system' function, used in panic() to reduce processor energy used.

Serial KDP supports now reading memory (badly. Need to fix this so it's done without causing data aborts. Probably fixing ml_nofault_copy would be a good idea...)

See changes from GenericBooter, add support for /chosen/firmware-version and such.

[OSFMK]
- Remove pmap_find_phys, was a return 0 anyway. Should probably be redone.
- Implement pmap_extract to return physical address for a virtual one.
- ml_nofault_copy is a lie.

[IOKIT]
- AppleARMPE now publishes the model name.

Initial kernel import. So many things are broken with this thing, who's willing to fix them all?
