There were two booleans that could be merged into the flag word.
This also fixes a bug with CHAN_NOSTOP not working for local sounds because it checked the wrong sound source for the playing sound.
src/d_main.cpp:280:18: warning: using the result of an assignment as a condition without parentheses [-Wparentheses]
src/rendering/r_videoscale.cpp:147:22: warning: comparison of integers of different signs: 'int' and 'unsigned long' [-Wsign-compare]
src/sound/s_reverbedit.cpp:250:18: warning: comparison of integers of different signs: 'size_t' (aka 'unsigned long') and 'int' [-Wsign-compare]
Notable changes:
* IsSourcePlayingSomething had undefined behavior when checking unattached and unpositioned sounds.
* loading Blood RAW sounds with different sample rates but the same backing lump may not use the same hardware sound buffer.
* when playing an unpositioned sound the attenuation is irrelevant and must be ignored. This resulted in a 3D sound being started which was mostly inaudible due to lack of valid origin.
- added Marisa Kirisame's CHAN_OVERLAP flag.
- exported S_IsActorPlayingSomething to ZScript.
The sound API change required deprecating A_PlaySound and S_Sound. There are now new variants S_StartSound and A_StartSound which have two distinct parameters for channel and flags.
Also simplified the sound init decision making. With FMod gone there is no reason to be pedantic here. Even the check of snd_backend for the Null device could be omitted here, its only realistic use is '-nosound'.
Many of the simple wrappers have been moved to a separate file and the sound source handling has been abstracted.
This is only the first phase, the work is not complete yet.
Also changed the license of the sound code to BSD after verifying that this code bears no similarity to id's original sound code anymore, save for a few function names (which are due to be refactored out anyway.)
This implementation only reads GIF, BMP and PIC formats. No animated GIF support because stb_image does not handle that.
PNG, JPG and TGA are still being handled by the existing dedicated implementations.
PSD and HDR are impractical for reading texture data and thus are disabled.
PnM could be enabled, if its identification semantics were stronger. stb_image only checks the first two characters which simply would falsely identify several flats with the right colors in the first two bytes.
This is more or less a waste product of getting stb_image to work with something actually testable, so it is just provided as-is.
Now there is only one single entry point for both, instead of previously 2 entry and 4 exit points.
This also eliminates the explicit shutdown of ZMusic. Timidity++'s two buffers have been put in containers that self-destruct on shutdown and calling dumb_exit is not necessary because the only feature requiring it is not used by any code in the music library.
FMod had MP3/Ogg playback integrated right into itself, and the OpenAL backend tried to replicate this functionality.
This functionality, however, has been removed over two years ago when FMod started breaking things more and more, it was only this backing implementation that was left in.
This was the last player class.
This code was also cleaned up for non-Windows systems where CD Audio is not implemented.
Instead of providing an empty implementation, all related code is now explicitly deactivated.
It is now being handled by the controlling code.
While of no benefit for GZDoom itself, this finally allows to separate the entire music code into a separate, engine independent project that merely provides streamed music data when not playing on a hardware device (WinMM Midi or CD Audio.)
The tight coupling of the music code with the sound backend made this nearly impossible before
The way CDDA was treated as an afterthought made handling of stream songs somewhat problematic, because the state could be unclear.
CDDA is an easily identifiable format so it should be tested first.
This was getting a bit unwieldy. The include path setup is not perfect yet, that's work for later.
(It's about time we're getting C++20 with modules so that this include path madness can be put to an end.)
Also made the decode_vorbis function in DUMB a function pointer so that the library does not depend on high level code and can just ignore the vorbis case if no supported.
This isn't the final location but this means that the device is merely a data provider, with the sole exception of the Win32 MIDI device whose unwieldy usage requirements unfortunately dictate much of the needed interface here.
The sound font reader may not be deleted because its ownership is transferred to the instrument set.
The gus_patchdir variable was not transferred to the config struct.

- renamed the FluidSetting functions to ChangeSetting so that they can be used as a generic means to change music player options without overloading the virtual function table for each minor thing.
- pass Printf as a parameter to the MIDI renderer to uncouple it from the main GZDoom code.
- throw exceptions when setting up the renderer fails so that this can be handled consistently for all construction errors here.
- delete FluidSynth handles before the constructor aborts.
