Simon Sundberg cecd6b54f2 pping: Inital rate limit implementation ...

Add a per-flow rate limit, limiting how often new timestamp entries
can be created. As part of this, add per-flow state keeping track
of when last timestamp was created and last seen identifier for each
flow.

Additionally, remove timestamp entry as soon as RTT is
calculated, as last seen identifier is used to find first unique value
instead. Furthermore, remove packet_timestamp struct and only use
__u64 as timestamp, as used memeber is no longer needed.

This initial commit lacks cleanup of flow-state, user-configuration of
rate limit, mechanism to handle bursts etc.
