be75fed975 vp6: properly fail on unsupported feature 
Interlacing is not supported at all and mismanaged down the normal
codepaths causing possible buffer management issues.

6f40e9f070 x86inc: support stack mem allocation and re-alignment in PROLOGUE 
Use this in VP8/H264-8bit loopfilter functions so they can be used if
there is no aligned stack (e.g. MSVC 32bit or ICC 10.x).

02823f6d71 Make LOCAL_ALIGNED syntactically similar on all systems 
This changes the LOCAL_ALIGNED definition on systems where
DECLARE_ALIGNED is used so it matches the manual alignment
case, ensuring invalid use will not compile on x86 only to
fail on everything else.

2ddf7c88d1 ZeroCodec: Flip output 
The initial testing of the VFW binary codec was flawed,
likely due to an AviSynth bug.

Re-testing using VirtualDub and various professional editing
applications has revealed it should have been flipped.

9a2e79116d golomb: use unsigned arithmetics in svq3_get_ue_golomb() 
This prevents undefined behaviour of signed left shift if the coded
value is larger than 2^31. Large values are most likely invalid and
caused errors or by feeding random.

Validate every use of svq3_get_ue_golomb() and changed the place there
the return value was compared with negative numbers. dirac.c was clean,
fixed rv30 and svq3.

92dad6687f arm: fix use of uninitialised value in ff_fft_fixed_init_arm() 
When initialising an FFTContext for a plain FFT, mdct_bits is not set
and can contain a garbage value.  Since nbits is always valid and for
MDCT operation is mdct_bits - 2 checking this instead avoids using an
uninitialised value while having the same effect.
