52467047aa 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.

9ed0802914 Change the way efibootmgr works by specifying bootnum via -b parameter
Instead of passing the bootnum to each different parameter, require users
to specify -b when running operations that need a bootnum.

This allows activation of a new boot entry at the same time it's created
by adding -a onto the command line.

de26ba4d82 Add -b bootnum to allow creation of a specific boot number (rather
than the auotmatic selection). This is important in some scripting
environments.

Also, remove bogus checks for bootnum != 0. 0 is a valid bootnum.

83caf7e590 Remove ignored command line options
The --device and --part command line options were planned for Linux
compatibility mode. However, that mode will never happen, so remove
them as last vestiges of a false start.

51922c697b Improve printing the boot variables.
Print the boot variables in the order in the BootOrder variable, if it
exists, and then in verbose mode print any unreferneced BootXXXX
variables. If BootOrder isn't set, fall back to printing all the
variables.

96289d0961 Remove write-only opt and useless optlen variables.
This squashes the warning gebnerated by GCC 6.x. Since
variables that are now removed had come documentation
value, put relevant bits in comment, so they can be
resurrected from there when actually needed.

1285bcc833 Import Netflix's efibootmgr to help manage UEFI boot variables
efibootmgr manages the UEFI BootXXXX variables that implement the UEFI
Boot Manager protocol defined in the UEFI standards. It is modeled
after the Linux program of the same name with a mostly compatible set
of command line options. Since there's a fair amount of OS specifioc
code due to differeing names and methods of doing things, the
compatibility isn't 100%.

Basic functionality is implemented, though the more advanced next boot
functionality that's been defined elsewhere is unimplemented.
