Patch queue for efi - 2018-09-26

A lot of goodness in this release. We're *very* close to running the
UEFI Shell and SCT natively. The only missing piece are HII protocols.

  - FAT write support (needed for SCT)
  - improved FAT directory support (needed for SCT)
  - RTC support with QEMU -M virt
  - Sandbox support (run UEFI binaries in Linux - yay)
  - Proper UTF-16 support
  - EFI_UNICODE_COLLATION_PROTOCOL support (for UEFI Shell)
  - EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL support (for UEFI Shell)
  - Fix window size determination
  - Fix Tegra by explicitly unmapping RAM
  - Clean up handle entanglement
  - Lots of generic code cleanup
