A user who wishes to use default error concealment cannot set the
AV_EF_CRCCHECK flag because not every CRC in every format is a
reliable indicator of bitstream damage. In some formats crcrs
can be nonsensical in absence of any damage. We thus add the
AV_EF_CAREFUL flag in addition to the AV_EF_CRCCHECK flag to
allow a user to enable this reliable CRC check without having to
enable all CRC checks in all formats.

They use now code identical to the AAC decoder.
The AC3 decoder previously did not check the data_size and
the dca decoder checked against and set wrong values for float.
This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.
Depending on error_recognition is not correct, low values do
certainly not mean it is ok to crash.

This function is not tightly coupled to mdct, and it's in the way
of making a fixed-point mdct implementation.

This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

The "buf" pointer needs to be overwritten since otherwise the CRC check fails.
This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

None of these symbols should be accessed directly, so declare them as
hidden.

AVERROR(ENOMEM).
AVERROR_NOMEM is deprecated and will be dropped at the next libavutil
major bump.
