Add a SET_LTP call to allow on the fly activation/deactivation of the long term
...
predictor even in high complexity mode (LTP off is more loss robust), fix the
case where turning on LTP on a running stream can cause prediction against
bogus data by delaying the usage of the LTP until enough data has been encoded.

API: Change celt_encode and celt_encode_float so that they take an optional synthesis parameter after the PCM input. If optional_synthesis is null the encoder will be able to save some computation. If optional_synthesis is non-null if will be used to write the encoder's expectation of the decoder's output. Synthesis may alias the input pcm, so calling the encoder with the same buffer twice will achieve the old behavior. Remove 'restrict' from the CTL prototype.
