a5bfa66df5 x86: fft: replace call to memcpy by a loop 
The function call was a mess to handle, and memcpy cannot make
the assumptions we do in the new code.

Tested on an IMC sample: 430c -> 370c.

fa84506177 dxva2: include dxva.h if found 
Apparently, some build environments require dxva.h even for dxva2,
while others lack this header entirely.  Including it conditionally
allows building in both cases.

ea1c5011b3 dxva2_h264: fix signaling of mbaff frames 
The MBAFF flag may only be signaled if we're actually dealing with
a full frame, and not singular fields, as it can happen in mixed content.

a50b756280 lavc: remove stats_in from AVCodecContext options table. 
Its documentation states that it is allocated/freed by the caller, but
it is declared as an AV_OPT_TYPE_STRING AVOption. Since
367732832faaf1bac4ece37cf7fef8c911e16312 the AVOptions system frees
strings automatically. This can be considered an API break, since it
won't work when the caller doesn't use av_malloc() to allocate the
memory or wants to use the string after closing the codec.

Since there is not much value in this field being an AVOption, the best
solution is to remove it from the options table.

cac4760bf4 iac: generate codec tables as they are supposed to be 
Unlike its predecessor, Indeo Audio codec generates tables depending on
sampling rate. Previously decoder used pre-generated tables for 22050 Hz
which obviously doesn't work with other frequencies.

Many thanks to Maxim Poliakovsky for providing all needed information
for this.

b56825c40e mpc8: fix maximum bands handling 
In Musepack SV8 codec property tell the maximum nonzero band, but every
frame codes maximum band as a limit (i.e. strictly less than given value).
Synthesis also expects maximum nonzero band, so there's a need to convert
