0366664ef9 lavc: check channel count after decoder init 
Ensures the decoder did not set channel count to an insanely high value
during initialization, which could cause large memory usage when it tries to
get a buffer during decoding.

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

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.
