19c33d71c6 Remove unnecessary value check 
Due to the way the `render` function was rewritten in eabf971, the audio
variable is always going to be an array of `AudioSample`s, so a check to
see if it is equal to `nothing` is no longer applicable.

0cd33b8289 Stop trying to read from audio file if no data is available 
As soon as libsndfile has finished reading a file it no longer returns
any data. This can send the `render` method for `FileRenderer` into an
infinite loop. This way if not enough data is available a partial buffer
is returned.

7831578955 Add mono audio input to PortAudio shim 
The way the PortAudio callback works it is possible to reuse the buffer
used for sharing output audio data between Julia and the C-library.

The output data can be pushed from the shared buffer to the PortAudio's
output buffer, after which the same location in the buffer can be used
for storing the data read from the input buffer.

This does assume equal lengths for the in- and output buffers.
