This has some new things in it:
- various build fixes for several compilers
- hopefully getting SATA PMP IDs right
- Reworked makefiles
- better handling of device node numbers
- devices mounted at more than one path work now
- make -j works better now
- lots of device path fixes
- fixes to efivar -L
- better nvme handling in libefiboot
- efivar (and libefivar) will now work transparently with immutable
  efivarfs files.
