audio_wav_parse_hdr: handle zero-length data files again

the previous clean up turns zero-length data into no data and thus
an error, instead of simply doing nothing. noted by gson.

fix some sizeof() confusion.

using "const char search[4]" as a function parameter means that
"search" is actually a pointer type so "sizeof search" returns
8 on 64-bit platforms. i mis-read this and used "sizeof *search"
which is always 1, noted by rillig.

instead of trying to avoid writing "4" twice, put it in a define
and use that in various places instead. annoying.

audioplay(1): handle mis-aligned RIFF chunks.

put the code to find RIFF chunks into a new find_riff_chunk() function,
and handle mis-aligned chunk lengths. can now play files with chunks
that say they are 7 bytes long, and have 1 byte padding.

add some -V -V extra-verbose for the wav parser.

minor clean up in the RIFF/WAVE header checking.

use memcmp() not strncmp() to check for "RIFF" and "WAVE".
avoid endian convesion on part.len 3 times.

be sure to byte swap ext.len when checking/printing it.
