26f548bb59 fft: remove inline wrappers for function pointers
This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

c73d99e672 Separate format conversion DSP functions from DSPContext.
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

925aa96915 Second hunk from secrity fix from google.
The hunk is not fully understood but it just makes a check tighter so its
safer for us to apply until it is fully understood.

Might fix issue 2550 (and Chrome issue 68115 and unknown CERT issues).
Our bugtracker issue though should stay open until this has been fully
investiagted

8455e8c7c0 vorbisdec: Fix floor1 decoding
An intermediate value in the floor 1 linear interpolation was
overflowing
resulting in obvious artifacts on some files.

e.g.
http://upload.wikimedia.org/wikipedia/commons/7/79/Big_Buck_Bunny_small.ogv

Prior to this fix 87 out of 128 64kbit/s mono files decoded with ffmpeg
have
lower PEAQ ODG values than the same files decoded with libvorbis. With
this
fix none of that set have significantly worse ODG values than libvorbis.

Fixes issue 2352

c740f737e9 vorbisdec: Use int instead of uint16_fast_t for index variables
uint16_fast_t is unsigned int (or long) on Linux, which when compared
with int results in an unsigned compare.
