The C version is set in ff_dct_encode_init(), yet the MIPS version
is set in dct_init() (in ff_mpv_common_init() and therefore also
for decoders). This commit fixes this inconsistency.

The code was written in 2012, but seems to have been broken
for just as long. Compilation is broken on every MIPS/MIPS64
system with an FPU (which the code depends on).
The function is called only internally in DSP, so we do not
need to expose it.
apply_ltp on MIPS uses this function, but due to the function
being just a glue function with no real optimizations,
duplicate it there.
Up until now, there was one AACDecContext for the fixed
and one for the floating point decoder. These differed
mostly in certain arrays which were int for the fixed-point
and float for the floating point decoder; there were also
differences in corresponding function pointers.
Yet in order to deduplicate the enormous amount of currently
duplicated code between the float and the fixed-point decoder,
one needs common contexts. Given that int and float have the
same size on all common systems, this commit replaces these
arrays by unions of int arrays and of float arrays. The names
of these arrays have been chosen to be compatible with
AAC_RENAME().

Each ChannelElement contains exactly one SpectralBandReplication
structure; the latter structure contains lots of buffers
whose size depend upon USE_FIXED (i.e. AAC_FLOAT arrays).
This complicates deduplicating the parts of the AAC decoder
that are duplicated between the fixed-point and the floating
point decoder.
In order to fix this, the SpectralBandReplication structure
will be moved from the part of ChannelElement visible to
the common code. Therefore the ff_aac_sbr_* functions
are ported to accept a ChannelElement*; they will then have
to translate that to the corresponding SpectralBandReplication*
themselves (which is possible, because there are floating-point
and fixed-point versions of these functions).
While just at it, also ensure that these functions are properly
namespaced.

ff_aac_coder_init_mips() modifies a static const structure of
function pointers. This will crash if the binary uses relro
and is a data race in any case.
Furthermore it points to a maintainability issue: The
AACCoefficientsEncoder structures have been constified
in commit fd9212f2ed,
a Libav commit merged in 318778de9e.
Libav did not have the MIPS-specific AAC code and so this was
fine for them; yet FFmpeg had them, but this was not recognized.
Commit 75a099fc73 points to another
maintainability issue: Contrary to ordinary DSP code, this code
here is way more complex and needs to be constantly kept in sync
with the ordinary code which it mimicks and replaces. Said commit
is the only commit actually changing aaccoder.c in the last few
years and the same change has not been performed for the MIPS
clone; before that, it even happened several times that the mips
code was broken due to changes of the generic code (see commits
97437bd17a and
de262d018d or
860dbe0275 or
933309a6ca or
b65ffa316e). This might even lead
to scenarios where someone changing non-dsp aacenc code would
have to modify mips inline asm in order to keep them in sync.
This is obviously a significant burden (if the AAC encoder were
actively developed).
Finally, the code does not even compile here due to errors like
"Error: float register should be even, was 1".

Otherwise aacenc.o gets pulled in by the aacencdsp checkasm
test and it in turn pulls the rest of lavc in.
Besides being bad size-wise this also has the downside that
it pulls in avpriv_(cga|vga16)_font from libavutil which are
marked as being imported from another library when building
libavcodec as a DLL and this breaks checkasm because it links
both lavc and lavu statically.

Besides simplifying address computations (it saves 432B of .text
in hevcdsp.o alone here) it also fixes undefined behaviour that
occurs if mx or my are 0 (happens when the filters are unused)
because they lead to an array index of -1 in the old code.
This happens in the checkasm-hevc_pel FATE-test.

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.

This patch replaces the transform used in AAC with lavu/tx and removes
the limitation on only being able to decode 960-sample files
with the float decoder.
This commit also removes a whole bunch of unnecessary and slow
lifting steps the decoder did to compensate for the poor accuracy
of the old integer transformation code.
Overall float decoder speedup on Zen 3 for 64kbps: 32%
Possible since 48ac225db2.
Furthermore, the current code would not work on mips
in case ff_lsp2polyf() were used outside of lsp.c,
because it is not compiled on mips since commit
3827a86eac at all;
instead it is overridden with a static av_always_inline
function which only works for the callers in lsp.c.

The HEVC decoder has both HEVCContext and HEVCLocalContext
structures. The latter is supposed to be the structure
containing the per-slicethread state.
Yet that is not how it is handled in practice: Each HEVCLocalContext
has a unique HEVCContext allocated for it and each of these
coincides except in exactly one field: The corresponding
HEVCLocalContext. This makes it possible to pass the HEVCContext
everywhere where logically a HEVCLocalContext should be used.
This commit stops doing this for lavc/hevcpred as well as
the corresponding mips code; the latter is untested.
