MHR-3: See main changes below.

Kernel: Improve Disk interfaces regarding the struct they're using (all of them are using MountpountInterface now)

SystemLib: Start adding PowerPC code to the SystemLib to be cross compiled
as a PEF FAT binary.

Kernel: Adding new builtins to support a wide range of hardware.
