usr.bin: remove unnecessary CONSTCOND, lint no longer needs it

Since 2021-01-31, lint no longer requires a CONSTCOND comment in a
do-while-0 statement since this is a common code pattern, especially in
statement-like macros.

make a fallthru comment GCC7 compatible.

branches: 1.32.2;
Sync usage with manpage.

if just parsing don't try to read the uninitialised device name,
or display the unit number.

add a "-s" option that sends an ALL_SOUNDS_OFF midi event. very
useful after an interrupted midiplay leaves notes on.

branches: 1.30.8; 1.30.14;
if not playing (-q mode), don't call ioctl() or try to use the results.
now -q mode works.

branches: 1.29.18;
- accept "midi0" as an alias for "0" to the -d flag
- verify that the requested unit exists before playing
- if the verbose flag is set, print the selected device name and unit #

branches: 1.28.2;
- add a SYSEX0 macro that does not override the initializers and use it
- fix whitespace
- make things static and eliminate unused functions

fix sign-compare and cast-qual issues

branches: 1.26.8;
Remove clause 3 and 4 from TNF licenses

branches: 1.25.18;
Um, pointer differences are ptrdiff_t, and there's already a
printf specifier for it (t), so use it instead.

The type for pointer difference varies between ports, on some it's
"long int" and on others "int", so cast via long and use %ld for printing.

The rest of merge from chap-midi branch. Version of midiplay that uses the
sequencer API definitions in sys/midiio.h (so there is a use example).
These produce the same (ABI) sequencer events as the OSS macros, but in
a more strongly-typed way; OSS API macros could be built on them and added
to the OSS compatibility header sys/soundcard.h but have not been, yet.

branches: 1.22.12;
Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

safer use of realloc

netbsd.org->NetBSD.org

Add NetBSD RCS Ids.

Make it play RMID files as well. From bin/20388, Quentin Garnier.

err/errx/warn/warnx do not need \n at the end

Take the default output unit from env MIDIUNIT.

Don't open sequencer device if we're not going to play.

Make -p select the right program. Fixes PR 14402, from itohy@netbsd.org.

fix a simple, but important bug for system exclusive messages.
(forgot to increase a pointer, if the message has over 6 bytes length.)

convert to use getprogname()

Cosmetic changes.

Add a -p flag to set the MIDI program. From lindroos@nls.fi.

Fix timer reset bug when playing multiple songs.

branches: 1.8.4;
Make the copyright header conform to the NetBSD template.

Add f flag to getopt() argument. Fixes PR 6335.
From Andreas Wrede <andreas@planix.com>

Handle SYSEX events.

Improve man page.

Handle MIDI files with running status correctly.

Fix type that prevented program and controller changes.

Make user tempo setting more sane.

Add a very simple MIDI player. No features, no fluff.
