thorpej 8bb2be2987 Add a PXE boot loader. PXE interface code is derived by code
written by Alfred Perlstein, Paul Saab, John Baldwin for FreeBSD.

Still needs some work, but this will load a kernel on a Soekris net4501.

Many thanks to Frank van der Linden and his simulator wizardry for
helping me debug the low-level startup code.
