Log:
[BOOTMGFW]
- Define some core boot library structures -- reverse engineered to be compatible with MS.
This is important if we want to load MS' own binaries for testing (such as
MemTest.Efi)
- Define basic BCD structures
- Start implementing EFI->Windows Boot Library conversion routines. Last part remaining
is EFI path conversion.
- Fix linking with RTL, by providing some stubs for now.
