Stealing shamelessly from the panda/board.c file, add equivalent
support for checking for the default environment and automounting the
/boot partition on the SD card.
Also, include the necessary header files for this, and fix the
filename reference at the top of the file.

a quick and dirty theft of code from panda/board.c, it builds and
boots and appears to work. thoughts?

Keeping this sequence, in init scripts makes things more & easily configurable.

i agree, it was a bad idea of mine. so moving it *out* of the panda
code would make sense as well, yes?
