*****************************************************************************
*** Next ***
- NEW: Added a "BufferedSIODriver" class that implements the behavior of the
legacy Serial driver on top of a SIO implementation (buffering, events
and all).
- NEW: Added __CH_OWNEROF() macro to RT.
- NEW; Now hal.h includes cc_portab.h by default making it mandatory.
- NEW: Moved HAL serial error flags into asynchronous channels interface
