Anton Khirnov
a853388d2f hevc: change the stride of the MC buffer to be in bytes instead of elements 
Currently, the frame stride is passed in bytes, while the MC buffer size
is in int16_t elements, This can be confusing, so pass both strides in
bytes.

The src buffer should only contain values in the interval

Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in
the interval [0, 31], so no clip is needed.
