5a82ad644f svq1dec: Unbreak the scratch buffer allocation 
The input packets are always assumed to be padded and
the av_fast_ family of function takes a pointer to a pointer.

Thanks to Nicolas Dufresne <nicolas.dufresne@collabora.com> for
a similar patch.

Introduced in 7b588bb691.

4843a9c74f dpx: always write the image offset 
According to the DPX file format description found at
http://www.fileformat.info/format/dpx/egff.htm the ImageElement part of
the GenericImageHeader also contains an an offset to the real image data
beside the same member that can be found in the GenericFileHeader.

Libav keeps this member empty (=0) while some applications expects it to
be filled properly. FATE test updated accordingly.

b280c6202b arm: fft_vfp: Unify the behaviour in ff_fft_calc_vfp between arm/thumb 
Don't include the function pointer table in the code segment
in arm mode.

This shouldn't have any significant performance effect. It does
end up as a few more instructions than before, for ARM, but
only at the entry to this function, not within the fft functions
themselves.
