04581c8c77 x86: yasm: Use complete source path for macro helper %includes 
This is more consistent with the way we handle C #includes and
it simplifies the build system.

6860b4081d x86: include x86inc.asm in x86util.asm 
This is necessary to allow refactoring some x86util macros with cpuflags.

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
at startup.

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.

c4cccc8d3f h264: fix invalid pointer arithmetic 
Subtracting a (positive) value from the address of an array violates
C99 section 6.5.6:

  If both the pointer operand and the result point to elements of the
  same array object, or one past the last element of the array object,
  the evaluation shall not produce an overflow; otherwise, the
