449408d0c0 Add UCS2->UTF8 option.
Many UEFI variables are UCS2 strings (some NUL terminated, others
not). Add --utf8 (-u) to convert UCS2 strings to UTF8 before printing.

a4a8ff3e7d Finish implementing -d/--device/--device-path flag to print variable
as if it were a device path.

Remove language about a=b syntax on the command line. This will not be
implemented due to its limited usefulness. UEFI variables are binary
blobs, on the whole, and a simple work around exists for
strings. Clarify that the new value of the variable is taken from
stdin. Update manual with history.

081e8d8587 Fix building on i386 and arm. But 'public domain' headers on the files
with no creative content. Include "lost" changes from git:
o Use /dev/efi instead of /dev/efidev
o Remove redundant NULL checks.

ce703b2b4e Add efivar(1) to manipulate EFI variables. It uses a similar command
line interface to the Linux program, as well as adding a number of
useful features to make using it in shell scripts easier (since we
don't have a filesystem to fall back on interacting with).
