This changes some things to make code more readable (I really didn't know what the tmp_header was: now it is the "received_ptp_header". The commit simplifies allocation, because the tx and rx buffers are now part of ppi itself. We now have tx_ptp and tx_frame, both pointing within tx_buffer (and the same for rx). The pointers are the protocol side (aligned) and the argument passed to send/recv (which may be not be 4-aligned). At this point nothing changes, i.e. both gnu-linux flavours work and bare-i386 is not able to received.
