builds.

MFC r261309

Unbreak non-SMP builds. This was broken by r259284. Also, reorganize the
code introduced in that revision a bit.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Add hook called when every new processor is brought online -- including the
BSP -- so that platform modules have a chance to add the new CPU to any
internal bookkeeping.

Approved by: re (kib)

Add some platform KOBJ extensions and continue integrating PowerPC
hypervisor infrastructure support:
- Fix coexistence of multiple platform modules in the same kernel
- Allow platform modules to provide an SMP topology
- PowerPC hypervisors limit the amount of memory accessible in real mode.
Allow the platform modules to specify the maximum real-mode address,
and modify the bits of the kernel that need to allocate
real-mode-accessible buffers to respect this limits.

Factor out platform dependent things unrelated to device drivers into a
new platform module. These are probed in early boot, and have the
responsibility of determining the layout of physical memory, determining
the CPU timebase frequency, and handling the zoo of SMP mechanisms
found on PowerPC.

/* -> /*- for license, minor formatting changes

- removed obsolete ppc_exit/ppc_boot functions
- OpenFirmware returns overlapping memory regions. Use a simple
brute force algorithm to merge these into non-overlapping
regions. This fixes bugs in reporting of available memory
and also prevents pages from being added twice in the VM system.

Use the "shut-down" and "reset-all" Forth procedures to halt and
reboot, as calling OF_exit() just hangs a mac.

FreeBSD on my G4 800Mhz mac behaves identically to OSX for halt
and reboot now.

Get the correct memory regions from OpenFirmware. We were getting the
"available" ranges, not the "physical" ranges. Clean up some of the
bootstrap code in the process.
