*   Correctness fixes for fft_length parameter to `tf.spectral.rfft` &
    `tf.spectral.irfft`.
*   Exported model signatures using the 'predict' method will no longer have
    their input and output keys silently ignored and rewritten to 'inputs' and
    'outputs'. If a model was exported with different names before 1.2, and is
    now served with tensorflow/serving, it will accept requests using 'inputs'
