Subject: [PATCH] Remove CoreAudio device disconnect listener when closing
 input mode streams

The flag handle->disconnectListenerAdded[0] is never set to true for input
mode streams because the probeOpenStream() code uses
handle->disconnectListenerAdded[mode].

This causes RtAudio to never remove device disconnect listeners, which can
cause the listener slots to fill up and an "illegal instruction" error code
to be returned when you try to add a new one.
