Initial commit for ticket #929: Improve packet lost concealment (PLC) when handling burst of lost packets
WSOLA improvements:
- Introduce fade-out and fade-in effect
- Limit the number of continuous synthetic samples (only take effect when fading is used)
- Export many settings as macros:
- PJMEDIA_WSOLA_DELAY_MSEC (was HANNING_PTIME)
- PJMEDIA_WSOLA_TEMPLATE_LENGTH_MSEC (was TEMPLATE_PTIME)
- PJMEDIA_WSOLA_MAX_EXPAND_MSEC
PLC:
- added compile time macro PJMEDIA_WSOLA_PLC_NO_FADING to disable fading (default enabled)
Stream:
- fixed bug when stream is not PLC-ing subsequent packet loss (only the first)
- also add maximum PLC limit just as precaution if PLC doesn't limit number of synthetic frames
- unrelated: fixed warning about unused send_keep_alive() function
Delaybuf:
- modified to NOT use fading in WSOLA since we don't expect it to generate many continuous synthetic frames
