Since 596e5d4783, this is not necessary anymore. It also allows to
actually disable the flushing, improving write performance (but
possibly giving worse latency in real-time streaming).

This is enabled by default and can be disabled with
"-fflags -flush_packets".

mathops/x86: work around inline asm miscompilation with GCC 4.8.1
See: 659df32a9d

Previously the wrong buffer pointer was checked, when buf
instead of *buf was checked. But checking the return value
instead is even better.

If idx equaled num_coeffs - 1 on entry to the loop, the previous
check failed to break out of the loop.

If we really want to support parameter changes, they need to be
signalled along with the AVPackets as parameter change side data,
not just changing the AVCodecContext parameters when a packet
is demuxed (since there may be other earlier packets yet undecoded).
Something similar was already done for the sample rate in 0883109b2,
but some parameters were left changeable.
This avoids having to recheck the channel count for validity for
each decoded frame in (ad)pcm decoders, unless the decoders
explicitly say that they accept parameter changes.

Limit the size to INT_MAX/2 (for simplicity) to be sure that
size + BYTES_PER_FRAME_RECORD won't overflow.
Also factorize other existing error return paths.

This fixes the hypothetical case of rounding errors causing
incorrect values to be used.
We do not use *_EPSILON, because non trivial expressions can contain
errors larger than that making a zero equality test with *_EPSILON
unreliable.
