Andreas Rheinhardt 6f7bf64dbc avcodec: Remove DCT, FFT, MDCT and RDFT
They were replaced by TX from libavutil; the tremendous work
to get to this point (both creating TX as well as porting
the users of the components removed in this commit) was
completely performed by Lynne alone.

Removing the subsystems from configure may break some command lines,
because the --disable-fft etc. options are no longer recognized.

Andreas Rheinhardt 8387241975 avcodec/dct: Move fdct function declarations to fdctdsp.h
It is the more proper place for them given that this is
the only API using them.
Also use a forward-declaration of AVCodecContext in fdctdsp.h
to avoid including avcodec.h in jfdct(fst|int).c.

Diego Biurrun 95c0cec03a idctdsp: Add global function pointers for {add|put}_pixels_clamped functions
These function pointers already existed in the ARM code. Adding them globally
allows calls to the function pointers to access arch-optimized versions of the
functions transparently.

Diego Biurrun 060e4a9e06 dct/rdft: Remove duplicate typedefs for context structs
The typedefs also exist in the avfft.h header and since typedefs cannot be
legally redefined in C, the code fails to compile with some compilers.

This reverts commits 11c7155cce and 57f1b1dcc7.

thus making it more managable.
