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

loader: support for mixed-endianness ELF/loader and POWER8 On POWER8 with current petitpoot, the loader.kboot might be run as little-endian application. The FreeBSD kernel is always big-endian, so the load_elf_* routines must be aware of proper endianness of all fields.
