Subject: [PATCH 3/8] [TFRC/CCID3]: Remove now unused functions / function calls

This removes two things which now have become redundant:
 1. The function tfrc_rx_hist_entry_delete() is no longer referenced anywhere.
 2. The CCID3 HC-receiver still inserted timestamps, but received timestamps
    are not parsed/referenced/used by the HC-sender, it serves no function.

Signed-off-by: Gerrit Renker <gerrit@....abdn.ac.uk>
