lavc: fix mixing CODEC_ID/AV_CODEC_ID in C++ code.

Browse Source 
C++ does not allow to mix different enums, so e.g. code comparing
ACodecID with CodecID would fail to compile with gcc.

This very evil hack should fix this problem.

Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
To provide backwards compatibility, CodecID is now #defined as AVCodecID.
Note that this can break user code that includes avcodec.h and uses the
'CodecID' identifier. Such code should either #undef CodecID or stop using the
CodecID name.
