dccp tfrc: Receiver history initialisation routine
This patch
1) separates history allocation and initialisation, to facilitate early
loss detection (implemented by a subsequent patch);
2) removes duplication by using the existing tfrc_rx_hist_purge() if the
allocation fails. This is now possible, since the initialisation routine
3) zeroes out the entire history before using it.
