Janne Grunau 9ac44ad9d0 h264: check SPS entries directly to detect pixel format changes 
Comparing AVCodecContext.pix_fmt against the get_pixel_format() return
value has the side effect of calling the get_format() callback on each
slice. Users of the callback will probably handle hardware accelerator
initialization in the callback.

Ronald S. Bultje 8c53d39e7f lavc: introduce VideoDSPContext 
Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

Janne Grunau f1d8763a02 mpegvideo: allocate scratch buffers after linesize is known 
Since we can't know which stride a custom get_buffer() implementation is
going to use we have to allocate this scratch buffers after the linesize
is known. It was pretty safe for 8 bit per pixel pixel formats since we
always allocated memory for up to 16 bits per pixel. It broke hoever
with cmdutis.c's alloc_buffer() and high pixel bit depth since it
allocated larger edges than mpegvideo expected.

Fixes fuzzed sample nasa-8s2.ts_s244342.

Janne Grunau 61c6eef545 h264: prevent decoding of slice NALs in extradata 
It is not posible to call get_buffer during frame-mt codec
initialization. Libavformat might pass huge amounts of data as
extradata after parsing broken files. The 'extradata' for the fuzzed
sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains
multiple slices.
