Andreas Rheinhardt 66766bb1c7 avutil/avassert: Deprecate av_assert0_fpu() ...

Said function has presumably been added in order to check
that we have successfully reset the floating point state
after having violated the ABI/calling convention by not
issuing emms in our MMX DSP routines.

Yet the ability to check this should not have been made public,
because there is no external need for it and because the
function does not even always achieve what its documentation
claims to do: It only works when inline assembly is available.
It should have been implemented in emms.h like emms_c()
(which is where a replacement should be put if there is still
ABI-violating MMX code when av_assert0_fpu() is removed).
