2f2f5c6728 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.

35a419a2cb Exit when we can't print a variable.
Exit after printing a message on stderr when we can't get a
message. This is slightly different than linux, but keeps shell
scripts from thinking the value of the variable is the error message
and so is a net win.

b2a7ac4802 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.

4b844f8d99 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).
