Patch queue for efi - 2018-09-26

Browse source 
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
