POSIX::CBoard

Implemented the CBoard for POSIX. The CBoard includes following components:
32 Bit CLoIO read and write I/O simulation.
CAN interface simulation.

The simulated I/O and CAN output is directed to stdio, input read from stdin.
Read more about commands on the wiki page.

The POSIX CBoard shall be used for the development and the testing of the platform independent high layer units.
