Mathias Agopian 4e620ddce3 free EGL resources associated to a thread when it terminates
destroyed but current-to-a-thread resources are only destroyed
when they're made not-current; however, we were not destroying
those when the thread itself terminated, causing these resources
to be leaked forever.

we now install a tls-key destructor that takes care of this
by calling eglReleaseThread upon thread termination.
