This diff allows the user to send small programs to the EC and gain control of the lightbar. Right now, this is only exposed through ectool, and sysfs support will come later. To send a program to the EC, use $ ectool lightbar program /path/to/program.bin and then start running the program with $ ectool lightbar seq program BUG=None BRANCH=ToT TEST=Using the above steps with hand-assembled programs. Checked that infinite bytecode loops do not hang the EC. Checked that bad opcodes exit with an error. Stress tested pushing programs and changing sequences.
