This simplifications also fixes a few bugs in the PLC (hope it didn't create some new ones).

ca6533cd88 Energy quantization tuning.
Prediction coefficient now depends on the frame size. Also, the pdfs and means
have been adjusted and better quantized. This breaks compatibility of course.

6bf3b0a7a1 The coarse energy budget is no longer part of the bit-stream.
It is now the encoder's responsability to take care of it to avoid
busting the budget.
