Ticket #1042, minor updates related to AEC:
- Added requirement of AEC minimal latency between reference and echo in aectest sample app.
- Modified AEC latency in sound port to 3/4 of playback latency.
- Few cleaned up echo_common.c: unused vars, a bit stricter latency check (to be at least as much as PTIME).
