Fixing compiler warning for passing (unsigned char*) to (const char*)

* Add support for u8 bone indicies when loading glTF

* Fix segfault for glTF animations not keyframed at 0

When loading glTF animations we lerp between keyframes, and previously
assume that if the frame we are considering has a later keyframe, there
must be a previous keyframe. This is not true if the animation's first
keyframe is some time into the animation. In this case we now
effectively clamp to that first keyframe for any time prior to it.

* Respect parent bones tranform when loading glTF animations

We previously assumed that when loading glTF animations, the bones were
ordered with those higher up the skeleton tree (i.e. closer to the root)
came first in the list of nodes. This may not be true, so now we
repeatedly loop, preparing each level of the skeleton tree one after the
other, starting at the root level. This ensures that any parent
transforms are applied before transforming any child bones.

We also ensure that we have forced the loading of animation data before
attempting to interpolate to generate the animation frames for use
later, without this no animations are applied.

Finally we remove the check that assumed the first node in the nodes
list is the root, and use an invalid index value as the sentinal value
for when a node has no parent. Previously this was 0, which made
distinguishing between root nodes and children of the first node
impossible.

* 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

Actually, it seems more logical that rlgl takes care of OpenGL data than the models module...

Also, models module loaded vertex data is unloaded by models module.

hey!
Ive made a Raylib Binding for my Programming language ReCT! Its still a fairly small language (~30 users) but it would be really cool to be featured here, tho I'd completely understand if only relevant languages are allowed on the list

* Fixing typecast warnings generated by visual studio 2019 in examples.

* Changes to fixes based on feedback

* Fixed DrawLineEx

Corrected the issue https://github.com/raysan5/raylib/issues/1596

* Removed raymath dependency for DrawLineEx

Mostly typecasts, and some int to unsigned short changes, and including the windsock 2 library in the examples.

* More warning fixes for physics and math

* fix a crash introduced with the warning changed.

While it is JavaScript, I'd rather this be named raylib-duktape since there are different implementations of javascript available. Like QuickJS, V7, or Node.js.

* Add MUSIC_AUDIO_NONE to MusicContextType and format fixes
- Useful to check the context type to see if the format is recognized. Defaulting to wav causes issues where formats are assumed to
be wav.

* Fix memory issues with LoadMusicStream and UnloadMusicStream
- Set ctxType and ctxData even if the format fails to load.
- Set ctxData to NULL if it fails and check for null inside UnloadMusicStream.
- Change RL_MALLOC when loading formats to RL_CALLOC to prevent undefined behavior.
- Add NULL check when unloading xm file.

-Checks for absolute pressure in absolute events to simulate a touch or a left mouse click.
-Updates touch position on absolute events.

Sorry if this is a bit of a useless pr
