Get the Android Java Native Interface Environment of the current thread.
This is the JNIEnv one needs to access the Java virtual machine from native
code, and is needed for many Android APIs to be usable from C.
The prototype of the function in SDL's code actually declare a void* return
type, even if the implementation returns a pointer to a JNIEnv. The
rationale being that the SDL headers can avoid including jni.h.
A pointer to Java native interface object (JNIEnv) to which the
current thread is attached, or NULL on failure; call
SDL_GetError() for more information.
Threadsafety:
It is safe to call this function from any thread.
