audioplay.1: generalize a reference to web browsers

Remove list of audio drivers, moved to audio(4).

samples on platforms that have these types natively, and
can handle signed linear 32 bit samples. explicitly

XXX fix support for unsigned linear samples -- it seems they need
to be converted to signed for WAV???

- add rudimentary "wav" recording support: don't think it copes with
big-endian systems properly yet -- need to add RIFX support or swap
samples while writing. more on this coming soon.

- new "-F <format>" option for audiorecord. supported values of <format>
are "sun", "wav" and "none", plus a few aliases.

- split sun & wav support out into their own files.

- don't assume that WAV header elements are properly aligned for the
type of data they hold.

fix PR#18909, but not quite exactly the same as the patch provided. also,

read/write loop method.

Move close so that last ioctl is before close call.
Fix duplicate word in comment.
Based on patch from Christian Biere in PR 18902, with a style nit fixed.

print the file name in verbose mode as well. avoid printing (null) for encoding.

sweep of errx/warnx, remove unnecessary trailing \n

define: datasize == 0 means use the whole file. fixes part of PR#12809.

When we have to print usage instructions, don't indicate success in the exit

* Don't treat failure to open a file as fatal error; print a warning to
standard error, arrange for a non-zero exit status and continue with the
next file. Addresses PR bin/8748.
* GCC vs. ANSI: a cast doesn't yield an lvalue.
* Use MAP_FAILED.

fix bug introduced in 1.12:
only return a header length of 0 if we are using -f (force), not
in the case when we know how long the header is. this stops from
playing the audio header.
