Comment (by pbennett):

 Patch 006 deprecated AVStream::codec, avcodec_close,
 avcodec_get_context_defaults3

 Fixes AVStream::codec, avcodec_close, and avcodec_get_context_defaults3 in
 the rest of the mythtv programs and libraries (not plugins yet).

 Changes to avcodec_get_context_defaults3

 If avcodec_get_context_defaults3 occurs after
 avcodec_alloc_context3(codec), it is superfluous since
 avcodec_alloc_context3 already sets up the defaults. If it occurs in other
 cases it must change to avcodec_free_context and avcodec_alloc_context3
 since reusing an AVCodecContext is no longer supported.

 Also fixes one error introduced in mythavutil.cpp by the previous commit.

 This affects some areas that I cannot test or have not tested yet. These
 include Crystal HD and VDA output, transcoding, Airplay, nuppel video,
 MHEG, digital audio encoding.
