1df0b06162 nuv: Reuse the DSPContext from RTJpegContext 
There is no point in populating NuvContext with another DSPContext.

Also split static and dynamic initialization bits to avoid running the
static initialization parts over and over.

1b1094a19d vdpau: switch ff_vdpau_get_surface_id from Picture to AVFrame 
This gets rid of aliasing completely unrelated structs to Picture.

Fixes the remaining compilation warnings in the vdpau code.

7948a51b5c vdpau: don't assume Picture and H264Picture are the same 
The code passed H264Picture* and Picture*, and assumed the
hwaccel_picture_private field was in the same place in both
structs. Somehow this happened to work in Libav, but broke in
FFmpeg (and probably subtly breaks in Libav too).

634d9d8b39 arm: get_cabac inline asm 
Based on the aarch64 asm. CPU cycle counts on cortex-a9 compared to
gcc 4.8.2:
before: 475 decicycles in get_cabac_noinline, 67106035 runs, 2829 skips
after:  393 decicycles in get_cabac_noinline, 67106474 runs, 2390 skips

Overall speedup is above 2%. Code generated by clang 3.4 is slower on
the same hardware and the relative change is a little larger.

Based on the x86 branchless get_cabac asm. get_cabac_noinline() gets

from Xcode 5.1 beta5. More than 6% faster overall. A part of the overall
speedup might be explained by additional inlining of get_cabac().

4cb6964244 dcadec: simplify decoding of VQ high frequencies 
The vector dequantization has a test in a loop preventing effective SIMD
implementation. By moving it out of the loop, this loop can be DSPized.

Therefore, modify the current DSP implementation. In particular, the
DSP implementation no longer has to handle null loop sizes.

The decode_hf implementations have following timings:

For x86 Arrandale:
        C  SSE SSE2 SSE4
win32: 260 162  119  104
win64: 242 N/A   89   72

The arm NEON optimizations follow in a later patch as external asm. The
now unused check for the y modifier in arm inline asm is removed from
configure.

7686afd049 dca: factorize scaling in inverse ADPCM 
Based on a patch from Christophe Gisquet.

Unrolling of the m == 0 case avoids a possible use of the uninitilized
value sum when s->predictor_history is not set. I failed to find a
sample for it. It also reduced the cycle count from 220 to 150 on
sandy bridge, x86_64 linux, gcc 4.8.2 compared to his patch.

Timings for Arrandale:

win32:  2108   334
win64:  1152   322

Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with
the jmp destination being aligned.

Unrolling for ARCH_X86_64 is a 20 cycles gain.

98fdfa9970 ppc: reduce overreads when loading 8 pixels in altivec dsp functions 
Altivec can only load naturally aligned vectors. To handle possibly
unaligned data a second vector is loaded from an offset of the original
location and the data is recovered through a vector permutation.
Overreads are minimal if the offset for second load points to the last
element of data. This is 7 for loading eight 8-bit pixels and overreads
are reduced from 16 bytes to 8 bytes if the pixels are 64-bit aligned.
For unaligned pixels the overread is reduced from 23 bytes to 15 bytes
in the worst case.

c0c45188e5 mlp: improve request_channel_layout behavior. 
Don't decode further substreams if request_channel_layout
is a subset of the current substream's channel_layout.

Before, we would only discard further substreams if
request_channel_layout matched the substream's
channel_layout extactly, thus decoding additional
channels which the caller would probably end up downmixing.

5fdbfcb5b7 dcadsp: split lfe_dir cases

In addition, splitting them allows more optimized code, at least for x86.

5b59a9fc61 x86: dcadsp: implement int8x8_fmul_int32 
For the callable function (as opposed to the inline one):
         C  SSE  SSE2  SSE4
Win32:  47   42   29    26
Win64:  30   33   25    23
The SSE version is neither compiled nor set for ARCH_X86_64, as the
inlinable function takes over.

2bd44cb705 dcadsp: add int8x8_fmul_int32 to dsp context 
It is currently declared as a macro who is set to inlinable functions,
among which a Neon and a default C implementations.

Add a DSP parameter to each inline function, unused except by the
default C implementation which calls a function from the DSP context.

On an Arrandale CPU, gain for an inlined SSE2 function vs. a call:
- Win32: 29 to 26 cycles
- Win64: 25 to 23 cycles
