Allow loader to load 64-bit ELFv2 PowerPC kernels.

Relocate kernel to high address space (a static + 64 MB for now) to avoid
conflicts with the Linux host kernel. This lets you kexec an unmodified
GENERIC64.

Add kexec-based Linux shim loader for use with the firmware petitboot
loader on PS3 and POWER8 systems. This is reasonably portable to other
architectures, especially FDT-based ones, if similar features are useful
elsewhere.

Netboot support is missing for now and will be added in a future commit,
at which time loader.ps3 will be garbage collected.

Done at: Hackathon

Finish TODOs. This boots a functioning kernel on PS3 -- and one that can
print Hello World on POWER8.

Commit the actually correct changes to get the FDT into the kernel.

Create FDT from /proc/device-tree on Linux host. This is enough to get into
KDB.

Get FreeBSD kexec'ing. The trampoline needs to relocate the kernel back to
where it is supposed to be (on top of Linux, usually) for this to actually
do anything useful, but we're now getting much closer.

Lay out first steps for launch trampoline.

Get the kernel loaded into some kexec_segments. The next hazard here is
to write the equivalent of the kexec purgatory code to call into the kernel
with useful arguments. The particular difficulty is in compiling a working
device tree from the host kernel.

Add some initial bits, enough to print out the loader greeting. This uses
FreeBSD syscalls for now, but with changes to the numbers, it also works on
Linux.

Disk and network IO are the next steps.
