avfft: avoid overreads with RDFT API users 
The new API requires an extra array member at the very end,
which old API users did not do.

This disables in-place RDFT transforms and instead
does the transform out of place by copying once, there shouldn't
be a significant loss of speed as our in-place FFT requires a reorder
which is likely more expensive in the majority of cases to do.

e3b355c0be avutil/mem: Don't include avutil.h 
It is not necessary at all. So remove it.
This also breaks an inclusion cycle mem.h->avutil.h->common.h->mem.h.

0aded9484d Move dct and rdft definitions to separate files 
This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.
