Michael Niedermayer d3585c53de avutil/softfloat: Move av_sincos_sf() from header to c file
The function is quite big and trigonometric functions should not really
be used in speed critical code

Nedeljko Babic f4ccf38902 libavutil/softfloat: Change order of fields in SoftFloat structure.

This change is needed in order to more easily integrate ffmpegs softfloat in
already developed algorithm for AAC.

Stefano Sabatini 987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
