Subject: [PATCH 2/7] [TFRC]: Loss interval code needs the macros/inlines that were moved

From: Gerrit Renker <gerrit@....abdn.ac.uk>

This moves the inlines (which were previously declared as macros) back into
packet_history.h since the loss detection code needs to be able to read entries
from the RX history in order to create the relevant loss entries: it needs at
least tfrc_rx_hist_loss_prev() and tfrc_rx_hist_last_rcv(), which in turn
require the definition of the other inlines (macros).
