Initial commit of an external serial flasher protocol

Supports RS-232, USB serial converters (untested) and TCP streams.

All functionality is stubbed out to allow multiplatform compile testing
of the headers we use.
The real serial flasher protocol driver will be committed next.

Corresponding to flashrom svn r625.
