Subject: [PATCH 5/7] [TFRC]: CCID3 (and CCID4) needs to access these inlines
From: Gerrit Renker <gerrit@....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.
