This is consistent with the rest of libavcodec.

Check whether CQ level is within qmin..qmax and abort on error. If this isn't properly
set, encoding will fail at the first frame.

  dsputil_alpha.h: Add missing stddef.h header to fix standalone compilation
Merged-by: Michael Niedermayer <michaelni@gmx.at>

The specification does not prevent an encoder to write the amplitude 0
as 0 amplitude_bits.

Our get_bits() implementation might not support a zero sized read
properly, thus the additional branch.

Rate and order must not be 0 even if the specification does not say that
explicitly.

Use the commonly used "if (!var)" instead of "if (var == 0)".

The value is used to calculate output LSP curve and a division by zero
and out of array accesses would occur.

Reflect the type of the corresponding field in lavc/lavfi.

Allow to select sample rates.

"channels" is an int in all the other places in the libraries, and the
av_frame_*_channels() accessors return and set an int, so this should not
implicate ABI breaks.

This avoids per parameter changes in ffmpeg at the cost of making access
somewhat more annoying.
