* Flip release of buffer;

First it needs to be taken out of the processing chain, then it can be released. The inverse of the initialization.

* Add mutex locks to audio buffer functions; Separate those used from both threads

* Flip release of buffer;

First it needs to be taken out of the processing chain, then it can be released. The inverse of the initialization.

* Remove TODO marker; The buffer is in stopped state and its data won't be accessed

* Add mutex locks to music/stream functions directly operating on buffer

* Secure UpdateMusicStream/PlayMusicStream/UpdateAudioStream;

This change is twofold:
* Add locks to UpdateMusicStream/UpdateAudioStream (second one needed separation)
* Remove unnecessary hack to restart music - inlining the statements resulted in a no-op

Especially the second part made it easier to ensure thread-safety overall

* Remove redundant check; Already checked at beginning of function

- Review formatting
 - Improve readability for some functions result return
 - Minimize early returns
 - Align LoadFileData() to UnloadFileData()

Fixes some crashes, e.g. calling StopMusicStream after trying to load Music from a non-existant .mp3 file

`char *txtData = (char *)RL_CALLOC(waveDataSize * 6 + 2000, sizeof(char));`

assumes every chunk being added to txtData is 6 bytes. This is not always true, sometimes a newline is involved and the data becomes 12 bytes instead, and this can cause a random segfault.

This commit changes `6` to `12`, and explains why in the comment.

* Added GetFileNameWithoutExt, GetFileName & strprbrk to raudio.c

* Gave return values to SaveFileData & SaveFileText in raudio.c

* Disable unused miniaudio features

* Fix mistakes

Additionally added a volume assignment from old to new as currently there is no way to get the volume of a sound and the AudioBuffer struct is not reachable from user code due to opaque definition.

It feels a little unfinished when you can SetMasterVolume but can't
really Get it. So to finish the symmetry here is the GetMasterVolume
implementation.

* Add a function to clone a sound and share data with another sound.

* rename items based on feedback

* PR Feedback, use custom unload for sound alias, not variant of normal sound unloading

* Update raudio.c

Review `raudio.c`: rewritten `ExportWaveAsCode()` to be more like rtextures.c `ExportImageAsCode()'

* no tab november

accidentally inserted a tab somewhere. corrected it.

* Add const qualifier to char * path argument
in qoa_open()

* Remove unnecessary cast

The `qoaplay_open()` function expects a `char *`, but we are passing in a `const char *`. While this works just fine, it does issue a compiler warning when strict:

```
src/raudio.c: In function ‘LoadMusicStream’:
src/raudio.c:1290:45: warning: passing argument 1 of ‘qoaplay_open’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
 1290 |         qoaplay_desc *ctxQoa = qoaplay_open(fileName);
      |                                             ^~~~~~~~
In file included from src/raudio.c:233:
src/external/qoaplay.c:86:34: note: expected ‘char *’ but argument is of type ‘const char *’
   86 | qoaplay_desc *qoaplay_open(char *path)
      |                            ~~~~~~^~~~
```

This change casts the argument to a `char *` to fix the warning.

It was quite restrictive and hacky implementation, just load multiple types same sound to play multiple instances.

Some format tweaks

It shouldn't matter much but it could avoid some conflicts with other libraries in the future (like `tinyfiledialogs`).

* Use RL_QUADS/RL_TRIANGLES for single-pixel drawing

Addresses problem mentioned in
https://github.com/raysan5/raylib/issues/2744#issuecomment-1273568263
(in short: when drawing pixels using DrawPixel{,V} in camera mode,
upscaled pixel becomes a line instead of bigger pixel)

* [rtextures] Fixed scaling down in ImageTextEx

Closes #2755

* Added global audio processor

* Renamed struct member to follow naming conventions

* Added example for AttachAudioMixedProcessor

* Fixed some grammar mistakes.

* Fixed some typos.

Switch to official `stb_vorbis.c` instead of using an outdated fork
