Timeout when writing output samples throughout the audio pipeline
...
This allows the audio pipeline to remain responsive even when the drain
buffer has completely filled. This in turn means that you now see the
track info in the 'now playing' screen change if the current track
changes whilst you are paused.
Since I was fucking around a lot in the audio processor anyway, I also
added mono->stereo expansion so that playing mono tracks on Bluetooth no
longer destroys your ears.

Count samples going in and out of the drain buffer
...
This is a more accurate way of knowing which track is playing when, and
also simplifies a lot of fragile logic in audio_fsm

tweak pipeline buffers rather than i2s dma buffer

this maintains the bluetooth changes to buffer sizes, but keeps the most
important i2s buffer the same size

Use the libspeexdsp resampler

AFAICT it runs a little slower? but it's fixed point, and has much
better understood audio characteristics.
