82650adfef Regularize the Netflix copyright
Use recent best practices for Copyright form at the top of
the license:
1. Remove all the All Rights Reserved clauses on our stuff. Where we
   piggybacked others, use a separate line to make things clear.
2. Use "Netflix, Inc." everywhere.
3. Use a single line for the copyright for grep friendliness.
4. Use date ranges in all places for our stuff.

12401a5c63 Implenent --fromfile to read variable values when printing variables
So

./efivar --fromfile Boot0001.bin --print --load-option

will take the value from Boot0001.bin file and then decode it as if it
were a load-option. This is useful for debugging handling of such
variables that may be hanging the boot for some people.

eeb2e7d208 Simplify the efivar interface a little.
We started out having Linux compatible libefivar interfaces. This was
in anticipation of porting the GPL'd efibootmgr to FreeBSD via a
port. However, since we need that functionality in the base, that port
isn't going to happened. It also appears that efivar is a private
library that's not used much outside a command line util and
efibootmgr. Reduce compatibility with the Linux version a little by
removing the mode parameter to efi_set_variable (which was unused on
FreeBSD, and not set to something useful in the code we'd
written). Also remove some efi error routines that were never
implemented and existed only to placate early GPL efibootmgr porting
experiments.

efced04627 Create efi utility printing routines
Split out asciidump, utf8dump, bindump, and hexdump into a separate
file efiutil.c. Implement new efi_print_load_option for printing out
the EFI_LOADER_OPTION data structure used to specify different options
to the UEFI boot manager.

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.

b9c36019a9 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.

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).
