[PATCH 7/8] [TFRC]: CCID3 (and CCID4) needs to access these inlines

[Gerrit Renker <gerrit@erg.abdn.ac.uk>]

This moves two inlines back to packet_history.h: these are not private
to packet_history.c, but are needed by CCID3/4 to detect whether a new
loss is indicated, or whether a loss is already pending.
