Add arguments to options in long description.

minor consistency nit

.Nm does not need a dummy argument ("") before punctuation or

Be consistent about putting commas between items in an enumeration.

note about WAV sample conversions.

- add signed linear support to audiorecord's WAV support.
- swap big endian samples for WAV.
- update audioplay(1) and audiorecord(1) audio driver xrefs.

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.

XXX: still need to clean up libaudio interfaces a lot.

Sort sections, sort SEE ALSO, drop trailing '.' in SEE ALSO, use standard

Don't give .Os an argument, not even 'NetBSD' (default includes version).

Also, document the default encoding in the manpage.

This default is consistent with the default for audiorecord under solaris.

If not specified on the command line, attempt to fall back to the environment

record.c: don't use total_size in the header if is -1 (it's initial value)

move some more processing before opening the audio device. don't
default the encoding to ulaw; default it to what ever the device
has. the latter fixes PR#30612.

check that an output file is given before doing any other work.

- fix a bug in WAV conversions

WAV seems to be signed only; convert unsigned samples.

for sun output files, if we have unsigned or little endian data, convert
it to signed big endian data. pull in a modified copy of the kernels'
auconv.[ch] to help with this (and remove some home grown code that did
some of the same things.)

- add signed linear support to audiorecord's WAV support.
- swap big endian samples for WAV.
- update audioplay(1) and audiorecord(1) audio driver xrefs.
