They need to be exposed on `rlgl.h` header section (not implementation section) because with some specific use cases (custom config.h, rmodels module enabled), building fails otherwise.

Redesigned function to only consider separation between the end of vertical size of one line and the beginning of next line

The `RL_CULL_DISTANCE_` definition remains as the initial value
of the variables.

Basic usage can be:
```c
#include <raylib.h>
#include <rlgl.h>

rlSetClipPlanes(RL_CULL_DISTANCE_NEAR, MY_CULL_DISTANCE_FAR);

if (must_reset_clip_planes)
    rlSetClipPlanes(RL_CULL_DISTANCE_NEAR, RL_CULL_DISTANCE_FAR);
```

* Fix several non-functional `target_compile_definitions`

* Avoid hardcoding the default vertex attribute locations

* Implement functional `rlNormal3f`

* Add normal definitions for `DrawCube`

* Update the basic lighting example to use `DrawCube` and `DrawPlane`

* Remove support for 0.11.0, and make build script more idiomatic
+ remove all 0.11.0 compatibility functions
+ remove most LazyPath .path variants
  + I didn't touch emscripten, I don't know if its relative or absolute
+ change all absolute paths to use .cwd_relative
+ only use the builder allocator
+ have local dependencies use the package manager
+ make adding raygui more flexible
+ use zig-cache for generated wayland files

* Remove support for 0.11.0 in examples/build.zig

* update examples further and add clarifying comment on addRaygui

Support all JOINT formats supported by glTF specs

* 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

This could be actually very tricky and GPU/drivers dependant...

For consistency, now _almost_ all `Draw*Lines()` functions use `RL_LINES` mode for drawing. It solves the linked issue but it can have other implications, as mentioned in the WARNING comment in `DrawRectangleLines()`.

Side note: `DrawRectangleRoundedLines()` now should be reviewed for consistency.

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

The way the current code worked was by calling `GetCurrentMonitor()`,
which would always return the monitor at position (0,0). This isn't the
primary monitor on all platforms, on Linux in particular it isn't the
case.

This isn't the case on the SDL backend, after calling `InitWindow()` the
window would always show up on the primary monitor. Even on the GLFW
backend, if the full screen flag was set it would attempt to put it on
the primary monitor as it would call `glfwGetPrimaryMonitor()` to do it,
so for consistency's sake we should do it on windowed mode too.

This reverts commit c1fd98591d.

The key handling in PLATFORM_DESKTOP_SDL was faulty in two ways, which
led to GetKeyPressed returning incorrect data.

CORE.Input.Keyboard.keyPressedQueue was updated only on SDL_TEXTINPUT,
meaning only text characters were registered as a pressed key, but not
function keys (eg. tab, backspace...). Also on such event, both
CORE.Input.Keyboard.keyPressedQueue and
CORE.Input.Keyboard.charPressedQueue were assigned the key's
corresponding codepoint, when CORE.Input.Keyboard.keyPressedQueue
should get the raylib keycode instead.

CORE.Input.Keyboard.keyPressedQueue is now updated on SDL_KEYDOWN event
instead.
