Subject: Re #1758: Initial implementation of OpenH264 wrapper. Supports:  -
 library detection via autoconf  - CBP  - packetization modes: 0, 1  - key
 frame request and indication  - obey remote's fmtp

Also added video codec test in samples (similar to the one in pjmedia test though).
And there are some fixes here and there too (e.g. in vid_codec_util.c).
