The simplified parsing currently in `mov_write_ac3_tag` trusts the content
of the packets a bit too much (the AC-3 parser returns all data fed to it,
including any possible data before the start code), while the existing E-AC-3
logic does proper header validation by utilizing the (E-)AC-3 parser.
Thus, normalize on AC-3 parser usage for both AC-3 and E-AC-3.
Difference to v2:
* libavcodec/Makefile received `STLIBOBJS-$(CONFIG_MOV_MUXER) += ac3_bitrate_tab.o`

Jan Ekström (6):
avcodec: make AC-3 bit rate table available in a separate header
{configure,avformat/movenc}: enable AC-3 parser for movenc
avformat/movenc: enable handle_eac3 to handle AC-3 tracks
avformat/movenc: move eac3_info definition so that it can be used for
AC-3
avformat/movenc: utilize existing AC-3 parsing workflow for AC-3
avformat/movenc: handle OOM situations when parsing AC-3 headers
