All known samples are actually ac3-in-spdif-in-wav, so use
the spdif demuxer to get the ac3 frames.

Some wav files report a data size that is bigger than the actual file size.
Fall back to estimation from bitrate in such cases.

If st is NULL, it means no 'fmt ' tag is found, but 'data' tag (which
needs a previous 'fmt ' tag to be parsed correctly and st initialized)
check will make sure st is never dereferenced in that case.

Fixes warning:
    libavformat/wav.c: In function ‘wav_read_header’:
    libavformat/wav.c:499:44: warning: ‘st’ may be used uninitialized in this function [-Wmaybe-uninitialized]

If there is a 'SMV0' tag, but no 'fmt' tag, it is possible that
'st' got used as NULL.

Also add missing trailing commas, break long codec_tag lines and
add spaces in codec_tag declarations.

Prefix the functions/tables brktimegm, pcm_read_seek,
dv_offset_reset, voc_get_packet, codec_movaudio_tags,
codec_movvideo_tags.

After this, lavf has no global symbols without the proper prefix.

Trivial replacements with sed are done in this commit:
sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'

Audio and video are interleaved via stream cur_dts - no idea how
reliable this is.
It also cannot display the video properly - it is stored with
about 15 in a single JPEG frame, I cannot think of a reasonable
way to implement this.

It's more readable and less prone to breakage.

Moving the search and parsing of the 'fmt ' info the main loop of
wav_read_header() allows tags that precede it to be parsed.  Creating
wav_parse_fmt_tag() makes wav_read_header() easier to read.

Since we want to break the loop the 'if (data_ofs < 0)' block is moved after the loop.
