bf58545aac audiodsp: fix vector_clipf documentation 
The x86 version processes 16 floats per iteration, so len must be a
multiple of 16.

eea9857bfd blockdsp: drop the high_bit_depth parameter 
It has no effect, since the code is supposed to operate the same way for
any bit depth.

75d98e30af audiodsp/x86: clear the high bits of the order parameter on 64bit 
Also change shl to add, since it can be faster on some CPUs.

cpb_size_scale which were not accounted for here.

de452e5037 pixblockdsp: Change type of stride parameters to ptrdiff_t 
This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

Also adjust parameter names to be "stride" everywhere.

75d642a944 vaapi_vp8: Explicitly include libva vp8 decode header 
With some old libva versions <va/va.h> does not automatically include

6755eb5b21 mss12: validate display dimensions 
The code currently reads the coded dimensions from the extradata, but
expects the display dimensions to be set by the caller, and does not
check that they are compatible (i.e. that the displayed size is smaller
than the coded size).

Make sure that when the display dimensions are set, they are also valid.
Fixes possible invalid memory access.
