{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

specifying whether only the exact supplied address is acceptable. If
false, the address is considered a hint only. It will be picked, if
available, otherwise a greater address is tried to be acquired, and
as last resort any address. This feature is only implemented for PPC.
It is needed since the preferred kernel text base address 0x80000000
might not be available (and actually isn't on my Mac mini).
* Fixed a bug in the PPC memory management code:
is_{virtual,physical}_allocated() were checking whether the given
range was completely contained by an existing range instead of
checking for intersection. As a consequence we could (and did) allocate
a range intersecting with already allocated ranges. The kernel segment
thus overwrote OF memory for instance.
* The ELF loader makes sure that it got both text and data segment of
the image to be loaded.
The PPC boot loader successfully loads kernel and modules now. Next
comes the hard part, I'm afraid.

kernel didn't count an empty structure, while the boot loader reserved
4 bytes for it - dunno why, a _PACKED everywhere didn't help; it's probably
a compile option issue.
To be on the safe side always, I've now added this dummy.

Removed the arch_mmu_alloc() function, added (empty) arch_mmu_free() function.
Added platform prototypes for allocating and freeing a region.
