* 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.

* 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

* Disabling WindowSizeCallback around fullscreen toggle.

#1294 fixed the issue that toggle fullscreen changes the screen size because of the WindowSizeCallback. The proposed edit by @raysan5 was to comment out WindowSizeCallback which I essentially simplified to disable the callback around the set window monitor functions.

The developers using the ToggleFullscreen function should be aware that they need to size the screen correctly on that same frame. Otherwise they should check if fullscreen and size properly using the GetMonitorWidth and GetMonitorHeight functions.

* Update core.c

Fix issue from merge

This solves issue #1322 which in my opinion was prematurely closed. As the monitor resolution is expected to be the maximum that the monitor supports. My change is that as per GLFW documentation you can get all current video modes sorted by max resolution. When you toggle fullscreen the first video mode returned would be the current screen resolution setup but that doesn't help if you want to know the maximum supported.

I don't like this solution but I think it's valid in the meantime....

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...

Try to avoid a possible false-positive memory leak...

This is to account for GLTF info being more like instructions on how to build your animation instead of verbose description of each pose.

This change helps some platforms produce fewer errors/warnings.

return value for all platforms

* Added example for gltf animation and split some functions for loading model animations into IQM and GLTF similar to how models are being loaded.

* Removed wrongly duplicated function

* Bone loading for gltf model (not working at this point)

* Loading info about vertex to joint connection but animation is still not working

* Skeleton and pose is correctly loaded. Need to communicate about interpolation in GLTF

* The model almost looks like a real person on animation.

* Fixed model loading with bones.

Also updated license info on the model.

* Cleaned up some code and updated examples.

* Fix identation issues

* Fix identation issues

* Fix identation issues

* Documenting the compiler flags

* Moved some android compiler flags and added documentation on them too.

* Some more restructuring.

Removed unnecessary comments that were self described by the code.
Added some more explanations around certain parts of CMake and especially around compiler flags.

CMake relied on this file for configurations and also was interfering in the regular config.h by having a separate definition if building with CMake. This was not entirely correct so instead we will define compile time definitions separately through CMake (CompileDefinitions.cmake) and also will use the provided EXTERNAL_CONFIG_FLAGS that I found that will not use config.h in through the build process.

I also introduced a new compiler option (CUSTOMIZE_BUILD) that when OFF will use the default config.h and when ON will show other options for redefining your own options.

Fixed an error in rlgl.h where if you have both RLGL_STANDALONE and SUPPORT_VR_SIMULATOR you get a compile time error.

This test file is just testing compilation with the library works correctly but is no longer needed because:
- it is not cross platform
- it taps into the CTest system which is better suited for real unit/integration tests
- it can be incorporated into the pipeline of github actions instead in the future

Upload mesh data to GPU and get VAO/VBO identifiers

As described in the official documentation https://cmake.org/cmake/help/v3.0/variable/BUILD_SHARED_LIBS.html this flag is global by default and controls if the library will be built as a shared or a static library allowing us to define only one call to the add_library function (without specifying its type). It is also added as an option to be visible in CMake GUI applications.
