- Created a pluggable COM layer - Converted COM + USART init into static initializers rather than typedefs - Generalized the USB HID COM API to match the USART API. - Changed USART and COM layers to be data driven rather than #ifdef'ing/switching on the specifics of each port git-svn-id: svn://svn.openpilot.org/OpenPilot/trunk@760 ebee16cc-31ac-478f-84a7-5cbb03baadba
