mixer(8): Implement hot-swapping

Introduce a -V option, which can be used alongside -d (default unit
change), in order to hot-swap devices (i.e switch to them on the fly
without needing to restart the track), in case virtual_oss(8) exists and
is running.

mixer(8): Improve mute and recsrc controls

The input options of "dev.mute" (+, -, ^) and "dev.recsrc" (+, -, ^, =)
are quite cryptic. Allow the input to also be an actual description of
what these options do.

+ -> add (recsrc)
- -> remove (recsrc)
^ -> toggle (recsrc, mute)
= -> set (recsrc)
0 -> off (mute)
1 -> on (mute)

Also, deprecate the use of the symbol options in the EXAMPLES section of
the man page, by using the new descriptive options.

In the future, we might want to get rid of the symbol options
altogether, but preserve backwards compatibility for now.

the "first mixer found", while the example shows how the change the
volume of the current mixer's "vol" device. Re-phrease sentence to
reflect the actual behavior of the command.

Also, improve the example by using the % operator, instead of hardcoding
0.05.

mixer(8): Allow full PCM device names as input for the -d option

The -d option is a wrapper around hw.snd.default_unit. Currently
mixer(8) expects the option argument to be just the unit's number (e.g
pcm0 -> 0). To avoid confusion, allow full device names of the form
"pcmN" as well.

While here, improve the -d option's description in the man page.

mixer: remove volume backwards compat, add % interpretation

The current situation is fairly confusing, where an integer is interpreted
as a percent until you slap a decimal on it and magically it becomes an
absolute value.

Let's have a flag day in 14.0 and remove this shim entirely. Setting with
percent can still be useful, so allow a trailing '%' to indicate as such.
As a side effect, we tighten down the format allowed in the volume a little
bit by ensuring there's no trailing garbage after the value once it's
separated into left and right components.

- Use Ta instead of a tab character in tables.
- Stylize all table headers with Sy consistency.
- Add a missing "vol" variant to the synopsis of "dev.volume".
- Sort dev.recsrc command modifiers consistency.
- Use "Bd -literal" for code blocks in the examples. "Bl -tag" is not
the right macro for that.
