spi: implement processing

Browse source 
Implement processing with writing to provided buffer or in-place
Fix types.
Add more PortInfo flags
Remove release-id, we now use a callback, which is more practical and
still allows deallocation out of the rt-threads if needed as well as
recycling the buffers into an atomic pool
Add more comments
Allow NULL in set_params to reset params
