  1. Proof-of-concept for "A/B" fallback booting 

    Add a tool (shimctl) that makes shim updates more robust by keeping two
copies of shim around (shimARCH.efi and shimARCH_b.efi).  Together with
shim-booted.service, it also supports tracking what versions of shim
were booted (and whether they were the "B" entry), enabling boot
counting.
