LibAudio: Add ClientConnection::async_enqueue()

async_enqueue() is a wrapper over the async_enqueue_buffer() call
to AudioServer. This allows users to asyncronously enqueue audio
samples, when the program requires non-blocking audio streaming.

This also makes ClientConnection use east-const everywhere.
