935279b855 avcodec/x86/vp3dsp_init: Set correct function pointer, fix crash 
Regression since fd17218558;
triggered by vp4/KTkvw8dg1J8.avi in the FATE suite, but not
when running fate as this code is not used when the bitexact
flag is set.

Bisecting done by ami_stuff, patch from user Mika Fischer
in ticket #10027 (which this commit fixes).

7c003b63c8 avcodec/x86/h264_idct: Fix incorrect xmm spilling on win64 
Broken in afa471d0ef. It just happened
to work before due to x86inc.asm previously performing XMM spills in
INIT_MMX mode which was more of a bug than an intentional feature.

782c4df28d x86: Avoid using 'd' as an argument name 
x86inc.asm adds defines for <argument_name>{b,w,d,q} which clashes with
the nasm d{b,w,d,q} pseudo-instructions for writing initialized data.

88b3b09afa avcodec/aacenc: Move initializing DSP out of aacenc.c 
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.

This also allows to remove ff_avg_pixels16_mmx,

7ed1e806e7 avcodec/x86/simple_idct: Empty MMX state in ff_simple_idct_mmx 
We currently mostly do not empty the MMX state in our MMX
DSP functions; instead we only do so before code that might
be using x87 code. This is a violation of the System V i386 ABI
(and maybe of other ABIs, too):
"The CPU shall be in x87 mode upon entry to a function. Therefore,
every function that uses the MMX registers is required to issue an
emms or femms instruction after using MMX registers, before returning
or calling another function." (See 2.2.1 in [1])
This patch does not intend to change all these functions to abide
by the ABI; it only does so for ff_simple_idct_mmx, as this
function can by called by external users, because it is exported
via the avdct API. Without this, the following fragment will
assert (on x86_32, as ff_simple_idct_mmx is not used on x64):
    int16_t __attribute__ ((aligned (16))) block[64];
    AVDCT *dct = avcodec_dct_alloc();
    dct->idct_algo = FF_IDCT_AUTO;
    avcodec_dct_init(dct);
    dct->idct(block);
    av_assert0_fpu();

6106fb2b4c avcodec/hevcdsp: Offset ff_hevc_.pel_filters to simplify addressing 
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.

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.

947d51f32a avcodec/x86/hpeldsp_vp3: Merge into hpeldsp 
Once upon a time, 413abbe164
added versions of some put_no_rnd_pixels functions for use
in VP3 and Theora (with an explicit check so that they are
only used for VP3 and Theora). When this was moved to hpeldsp
(from dsputil) in 3ced55d51c,
the check was replaced by a check for the bitexact flag
(and a CONFIG_VP3_DECODER compile-time check), so that
these functions were now used for other codecs as well.

Later commit 1dfc3cf89d
split off the "VP3-specific bits into a separate file",
yet these bits were not really VP3-specific bits at all
any more. (The error was repeated in commit
0a39c9ac0b.) This commit
has not been reverted, because this would make future
changes from Libav (from where it originated) harder,
yet Libav is no more, so this commit effectively reverts
1dfc3cf89d.

182663a58a get_cabac_inline_x86: Don't inline the assembly function on 32 bit 
While the inline cabac assembly has worked correctly in i386 builds
historically, modern compiler updates has started showing issues
with it, when the function gets inlined into larger contexts that
fail to provide the amount of free registers as this function
requires.

This was an issue with Clang on Windows on i386, which was fixed
in c6d284b945324a7bc70ea8b9056040c8148aa835. However, recently
the same issues also have started showing up with GCC (both for
Windows and Linux). Whether the issue appears seems dependent on
a lot of optimizer tuning (e.g. the issue appears or goes away
depenent on the combinaton of -march= and -mtune= options),
potentially due to the compiler making different decisions on
how much to inline.

Fixes: https://trac.ffmpeg.org/ticket/8903

x86: replace explicit REP_RETs with RETs 
From x86inc:
> On AMD cpus <=K10, an ordinary ret is slow if it immediately follows either
> a branch or a branch target. So switch to a 2-byte form of ret in that case.
> We can automatically detect "follows a branch", but not a branch target.
> (SSSE3 is a sufficient condition to know that your cpu doesn't have this problem.)

x86inc can automatically determine whether to use REP_RET rather than
REP in most of these cases, so impact is minimal. Additionally, a few
REP_RETs were used unnecessary, despite the return being nowhere near a
branch.

The only CPUs affected were AMD K10s, made between 2007 and 2011, 16
years ago and 12 years ago, respectively.

In the future, everyone involved with x86inc should consider dropping
REP_RETs altogether.
