Converting fprintf(stderr), printf, and printf_debug into a common print interface for flashrom

It also changes so -VV will spit out highly verbose messages for
debugging. This is a minimal patch to lessen impact a later patch will
convert current printf messages to the new interface.

Add file that was suppose to be committed with r835.

Corresponding to flashrom svn r836.
