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).
