Realtime safe buffer reference handling.

Turns out that dropping a shared_ptr is not realtime safe, even if you use
a realtime safe deleter.  Instead, instrusive_ptr is used for buffer
references, so a buffer reference may safely be dropped in the audio
thread (in which case it will be recycled by the BufferFactory).

Faster, cleaner, better.
