9e696d2e5f h264: support frame parameter changes during frame-mt

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.

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.

6b68223d31 cngdec: Allow flushing the decoder 
After a flush, don't average the output envelope and energy with
previous iterations.

Also start directly from the target values for the first iteration

95c89da36e Use ptrdiff_t instead of int for intra pred "stride" function parameter. 
This way, SIMD-optimized functions don't have to sign-extend their
stride argument manually to be able to do pointer arithmetic.

c285edd06e Remove usage of INIT_AVX in h264_intrapred_10bit.asm. 
Replace INIT_AVX by INIT_XMM avx. Port the whole file to use cpuflag
based function declarations. Remove (now unused) cputype argument in
function declaration macros. Change function prototypes to have mmx2
instead of mmxext as suffix, since that's required by cpuflags.

9b500b8f6c avcodec: Add a RFC 3389 comfort noise codec 
This isn't too useful as a normal codec, but can be used in
voip style applications. The decoder updates the noise
generator parameters when a packet is given to it for decoding,
but if called with an empty packet, it generates more noise
according to the last parameters.
