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.

246e0457d9 ("mixer.8: Add terse example
for increasing volume") mentions that the example changes the volume of
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.

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.

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.

command modifiers).
- Pet igor and mandoc -Tlint (e.g., start sentences after a newline).
- 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.
Fixes: 903873ce15 Implement and use new mixer(3) library for FreeBSD.
- use getopt(3) to parse command line arguments instead of home-made incomplete
parser;
- be more verbose when error in command line encountered (i.e. incorrect
playing/recording device, incorrect recsrc syntax).
