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.

a84fe06112 avcodec/idctdsp: Avoid inclusion of avcodec.h
Not every user of idctdsp.h wants to initialize an IDCTDSPContext;
e.g. the proresdsp only uses ff_init_scantable_permutation()
and the IDCT permutation enum; similarly for cavsdsp and wmv2dsp.
Using a forward declaration here avoids an avcodec.h dependency
in the relevant files.

It is not necessary at all. So remove it.
This also breaks an inclusion cycle mem.h->avutil.h->common.h->mem.h.

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.

4209216ee8 avcodec/mpegvideodsp: Make MpegVideoDSP MPEG-4 only
It is only used by gmc/gmc1 which is only used by the MPEG-4
decoder, so move it to Mpeg4DecContext and rename it
to Mpeg4VideoDSP. Also compile it iff the MPEG-4 decoder is compiled.

e84348a8ab avcodec/svq1enc: Add SVQ1EncDSPContext, make codec context private
Currently, SVQ1EncContext is defined in a header that is also
included by the arch-specific code that initializes the one
and only dsp function that this encoder uses directly.

But the arch-specific functions to set this dsp function
do not need anything from SVQ1EncContext. This commit therefore
adds a small SVQ1EncDSPContext whose only member is said
function pointer and renames svq1enc.h to svq1encdsp.h
to avoid exposing unnecessary internals to these init
functions (and the whole mpegvideo with it).

bbf045aa59 lavc/vorbisdec: use ptrdiff_t to iterate over intptr_t
While this probably never overflows, we are better safe than sorry.

The callback prototype should probably also use ptrdiff_t or size_t,
but I diggress (this would affect the DSP callback prototype).

The affected functions could also be changed into macros, this is the
smaller change to fix it though. And avoids (probably) less readable macros
The extra code should be optimized out when optimizations are done as all values
are known at build after inlining.

153fcd6de6 libavcodec/ppc: Fix HEVC AltiVec routines with --enable-small
GCC requires the argument to vec_splat_u32 to be a literal.  The easiest
way to accomplish this is to change 'shift' to be const in scale (as it
is in the transform routine above), and convert both routines to be
inline.  This way, GCC can coerce the values to literals.

Tested on a 970 (Apple G5) and POWER9 (Talos II); passed fate and played
a clip of Big Buck Bunny correctly.

Fixes ticket #7048
