Also switch all remaining headers over to #pragma once, and actually
use FB_COMMAND_SZ.

Implements a UDP protocol for fastboot, documented in
fastboot_protocol.txt.
This version of the protocol does not include multi-packet windowing,
which will likely be needed to achieve reasonable speeds over WiFi.
Since we don't have any WiFi use cases yet, we'd like to get this in
now and update the protocol later if it becomes necessary.
Usage:
fastboot -s udp:<hostname>[:port] <command>
