* Fix Undefined Symbol `_ftelli64`

* Add files via upload

* Update raylib.h

* Update raylib.h

Those functions were platform dependent and user has no control over the file created. They have been removed from raylib and just moved to `core_storage_values` example.

(GetMouseWheelMoveV).

REDESIGNED: `LoadDirectoryFiles()`
ADDED: `LoadDirectoryFilesEx()`
REDESIGNED: `LoadDroppedFiles()`
ADDED: `IsPathFile()`

This BIG BREAKING change simplifies the functions and gives more control to the user:
 - A new `struct FilePathList` has been added to avoid exposing complex pointers.
 - User is responsible of memory loading/unloading
 - Filepaths loading support recursive directories and file extension filters

* GetMonitorWidth()/GetMonitorHeight(): current video resolution instead max available

* adapt header comment to reflect change

RENAMED: `ClearDroppedFiles()` to `UnloadDroppedFiles()`

RENAMED: `ClearDirectoryFiles()` to `UnloadDirectoryFiles()`

Events waiting can be enabled/disabled, it toggles event polling.

When referring to byte array SIZE, I find it more clear than length

This feature is still under consideration/testing and it doesn't work properly, at least the Delay Effect processor.

WARNING: This addition is based on a PR and it's still under review, not sure if it will be maintained in the future. In general, raylib tries to avoid callbacks usage mechanisms.
