- Many functions renamed to follow rl*() convention
- Some internal functions exposed in the API
- Some functionality moved to other modules
- Reorganized all functions by categories
- Make sure it keeps working with OpenGL 1.1 and 2.1

* Add loop functions for music files.
Tell xm tracker to loop tracker when loop state changes.
Don't let looped xm tracker streams restart, they are infinite
Use modulo to make time tracker for xm looped streams work correctly.

* Remove loop functions, set XM loop in update based on flag.
Formatting cleanups.

- Some rlgl functions have been moved to core
 - Some functions have been made internal to rlgl
 - rlgl functions prefixed with rl*()

Vr simulator has been moved to core module and completely redesigned. Now user is in charge of stereo-render fbo and also in full control of distortion shader. Code is a bit more complex but better aligned with other raylib examples.

This function could be confusing depending on the context, it's better to let the user track the current active cursor

Now enum names are more consistent between them.

Just assigned a fixed memory size for custom Material parameters in case of being required, so we shouldn't worry about allocating/freeing them.

Some enums values have been renamed to be more consistent and also provide a more detailed description:
 - ShaderLocationIndex:    LOC_VERTEX_POSITION -> SHADER_SHADER_LOC_VERTEX_POSITION
 - ShaderUniformDataType:  UNIFORM_VEC2 -> SHADER_UNIFORM_VEC2
 - MaterialMapType: MAP_ALBEDO -> MATERIAL_MAP_ALBEDO
 - PixelFormat: UNCOMPRESSED_GRAYSCALE -> PIXELFORMAT_UNCOMPRESSED_GRAYSCALE

Removed memory allocation callbacks

NOTE: This feature is still under consideration and not complete.

RENAMED: TextureFilterMode values
RENAMED: TextureWrapMode values

RENAMED: CubemapLayoutType and NPatchType

* define SUPPORT_FILEFORMAT_MOD in config.h

* RLAPI LoadModuleFromData() definition in raylib.h

* LoadModuleFromData() definition in raudio.h

* LoadModuleFromData implementation in raudio.c

* Rename API to LoadMusicStreamFromMemory & default unload.

* raudio.c tabs to spaces

* Styling curly bracket and removing dev debugging TRACELOG

Current implementation is probably wrong and it should be reimplemented from scratch, in the meantime, I prefer to remove the function.

I feel nobody has ever used this function...

Upload mesh data to GPU and get VAO/VBO identifiers

* Added a new utility function to get the current monitor.

Some of the other functions rely on passing on a monitor id but we only have a function for querying the count of monitors available.

* Updated the comment to correctly reflect the function action

* Add quadratic bezier to shapes.c

* Add DrawLineBezierQuad to header

Removed function from raymath

Just for a better consistency

Exposing internal memory allocator/free, useful for advance users when required

Pefixing/Suffixing some data type identifier in the variables is not a convention used in raylib, just reviewed it for consistency...

Still, I kept the *Rec suffix in some functions.

Previous implementation did not consider any padding while drawing the characters on screen (despite being available on the font atlas), so, only minimum character area was drawn.

If some text effect shader was required (shadow, glow, outline...), there was no space in the drawn quad to draw that pixels effect.

This commit corrects that issue.

This is a BREAKING CHANGE!

To address the linked issue, several functions have been renamed and couterpart functions have been created to free loaded memory:
 - RENAMED: GetImageData() -> LoadImageColors()
 - RENAMED: GetImagePalette() -> LoadImagePalette()
 - RENAMED: GetWaveData() -> LoadWaveSamples()
 - ADDED: UnloadImageColors()
 - ADDED: UnloadImagePalette()
 - ADDED: UnloadWaveSamples()

Previous GetKeyPressed() method was actually returning unicode codepoints equivalent values instead of the key-code of the pressed key. So, it has been replaced by GetCharPressed(), returning unicode codepoints and GetKeyPressed() now returns key-codes.

Not implemented usage of this variable yet but already setup for the future... some functions require review to consider it on drawing...
