- Added iLBC codec (experimental) with the following features:

   - configurable default decoder mode (20 or 30),
   - encoder mode follows the mode specified in SDP fmtp from
     the remote's SDP,
   - silence detector uses pjmedia's,
   - PLC uses iLBC's PLC,
   - perceptual enhancement (penh) is configurable via codec
     param, as usual.

- iLBC mode is configurable in pjsua with --ilbc-mode option.

- Added packet lost simulation in pjmedia's UDP transport and
  in pjsua (with --rx-drop-pct and --tx-drop-pct options).

- Increase default buffer count in DirectSound to 32 frames
  to make it more resilient to CPU disruption.

- Specify and parse fmtp mode in SDP for codecs that need it.
