[core] eavesdrop: init L16 codec at right ptime in certain conditions.
[core] eavesdrop: avoid eavesdropping on itself and return error. [core] eavesdrop: adjust buffer operations for ptime mismatch and for when ptimes are the same. [core] eavesdrop: add buffering based on LCM (Least Common Multiple) when ptime mismatch, and have audio write thread enabled when ptime eavesdropee < ptime eavesdropper. [unit-tests] add unit-tests for eavesdrop.
