Only mono 16kHz is supported.

Only mono 8kHz is supported.

Ensures the decoder did not set channel count to an insanely high value
during initialization, which could cause large memory usage when it tries to
get a buffer during decoding.

Fixes typo in 2cbdd7c9.

This simplifies cpuflags porting.

It is only used in one place so there is no need for the abstraction.

Otherwise during scaling it will try to interpret input in the wrong way and
that leads to the test results disagreeing on different platforms and with
different optimizations.

Unlike YASM, NASM only looks for include files in the current
directory, not in the directory that included files reside in.

This is more consistent with the way we handle C #includes and
it simplifies the build system.

This is necessary to allow refactoring some x86util macros with cpuflags.

After a flush, don't average the output envelope and energy with
previous iterations.

Also start directly from the target values for the first iteration
at startup.

Previously the unit of the variable was Bov, not dBov.

This was a leftover from previous iterations of the code, where the
refl coef arrays were statically allocated.

I somehow messed up the placement of this one.

Some awk versions do not treat the result of unary + on a (numeric)
string as numeric, giving wrong results when used in a boolean context
Using unary - instead is logically equivalent works as expected.

With the input of Kostya and Ronald.

This is much faster with slow shells and noticeably faster even
with bash on a fast Linux system.

This way, SIMD-optimized functions don't have to sign-extend their
stride argument manually to be able to do pointer arithmetic.
