61884b9d1b wav: init st to NULL to avoid a false-positive warning.
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]

167f3b8de7 libavformat: Add an ff_ prefix to some lavf internal symbols
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.

7f84055e2d wav: refactor the 'fmt ' tag search and parsing.
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.

ca402f32e3 handle malloc failures in ff_get_wav_header
ff_get_wav_header is reading data from a WAVE file and then uses it
(without validation) to malloc a buffer. It then proceeded to read
data into the buffer, without verifying that the allocation succeeded.

To address this, change ff_get_wav_header to return an error if
allocation failed, and adapted all calling code to handle that error.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

462b26202b Set duration for wav files from sample size and data size or the wf64 sample value.
This should improve duration accuracy slightly and avoids a warning about its
