While the code layout comes from ptp-proposal, this is a different
package, now called pptp for "Portable PTP".

code was pruned from specific "ptp-proposal" protocol and the
skeleton of IEEE-1588 states was made. Next step is to insert,
step by step, the structs defined in ptpd. Still something needs
to be removed or renamed, but this should be a fair starting point.
