0c3339f4bd eac3dec: fix scaling 
This is the remaining error, the output on the SPX samples,
respectively csi_miami_stereo_128_spx.eac3 and
csi_miami_5.1_256_spx.eac3, goes from:
stddev:    8.71 PSNR: 77.52 MAXDIFF:  235
stddev:24270.51 PSNR: 22.17 MAXDIFF:47166
to:
stddev:    0.12 PSNR:114.12 MAXDIFF:    1
stddev:    0.12 PSNR:114.73 MAXDIFF:    1

4eb4451be1 x86: dct-test: fix compilation for prores 
When the decoder is deactivated, the x86-optimized versions are
not compiled, resulting in a link error.

The C version is unaffected, as it is part of the idctdsp
subsystem.

7b05b5093e ac3dec_fixed: always use the USE_FIXED=1 variant of the AC3DecodeContext 
The AC3DecodeContext has a float (USE_FIXED=0) and an integer
(USE_FIXED=1) variant, both of which can be present in the same binary.
This is not only very confusing, but it also breaks horribly, when one
variant is used by code expecting the other.

This currently happens, because eac3dec.c is only compiled for the float
variant, but also used from ac3dec_fixed.c, which uses the integer
variant.

The result is memory corruption, leading to crashes.

So compile eac3dec.c once for each variant and adapt it, so that it
works with the integer variant.

A loss of precission and scaling bug has been fixed by the committer

5a0e953c24 mjpeg: Mark decoder family as thread safe 
No global variables are used and the VLC tables are allocated without
static elements. This will allow using a JPEG decoding context within

117b432748 lavc: Introduce AVCodec internal capabilities 
This field is designed for marking codec properties useful to lavc internals.
Two internal capabilities are added:
 - FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks;
 - FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.
