Fix music visualizations to also work with audiotrack callbacks, which
stagefright uses. This slightly changes the way the data is stored,
since before we were relying on the buffers being written always
being at least 4K, whereas the callbacks are generally for smaller
amounts of data. Now we append all the data to a big circular buffer,
then return chunks of that buffer for visualization. When there are
multiple things playing at the same time, this will give the wrong
result, but (1) that was the case before as well, and (2) will be
fixed once we start visualizing the mixer output instead of the
mixer inputs.
