new boot infrastructure

  • more code and metadata unification
  • import of up-to-date implementations from the kernel
  • the boot loaders should behave more similarly on all platforms
  • support for deflate compressed (LZ77) boot components
    • this again allows feasible boot images to be created on mips32
  • IA64 is still not booting
    • the broken forked GNU EFI library has been removed, a replacement of the functionality is on its way
  • Property mode set to 100644
