New version of qbm that defaults to passing and elf32 and dtb to the
qemu to boot directly with out grub.

Constructs and ebbrt.dtb
Got rid of suprious print of file type
NOTE: currently passing commandline both via fdt and kernel command line (qemu --append)
Eventually when I add the app support for using the fdt verison I will remove this
from the qbm script
Hacks to make getopts work and also reorganized to have some common
src for all apps like the commandline processing code.
Forgot to commit common apps source directory and argv code
also added lint script from dan  probably needs updating
