ring: use 64 bit counters

Apparently, this messes up on wraparound (although it shouldn't). After
2^32 bytes an audio "blip" happens with AOs that use this ringbuffer.

Whatever, we can fix this by switching to a 64 bit counter. There's also
a good chance the ringbuffer will be dropped completely, so don't waste
more time on this.
