Fixes recent breakage of FEC decoding in the Opus codec.
Implement a new cache handling for ZRTP

The new ZRTP cache handling implements two main topics.

The first modification reduces the number of write requests to the external

The second modification implements a new handling of the RS2 data. This will
be a topic in an upcoming revised ZRTP specification.
