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.

get_byte           -> avio_r8
get_<type>         -> avio_r<type>
get_buffer         -> avio_read

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return
something useful.

c6610a216e Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. 
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
inaccuracy when accurate values are available. Idea by Frank Barchard
