In some conditions the allocation could run out of bits and attempt to allocate a negative number of pulses.

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.

Fix support for sample rates between 32kHz and 40kHz (lower rates are currently rejected, but work okay).

Allow all even frame sizes, change the selection of number of short MDCTs per frame to be more intelligent.

It is no slower with a large number of pulses, and as much as 30% faster with
 a large number of dimensions.

This lets us encode and decode directly from the pulse vector without an
 intermediate transformation.
This makes old streams undecodable.
Additionally, ncwrs_u32() has been sped up for large N by using the sliding
 recurrence from Mohorko et al.
ncwrs_u64 could be sped up in a similar manner, but would require a larger
 table of multiplicative inverses (or several 32x32->64 bit multiplies).
Note that U(N,M) is now everywhere 1/2 the value it used to be.
