hevc: rename hevc.[ch] to hevcdec.[ch]
...
This is more consistent with the rest of libav and frees up the hevc.h
name for decoder-independent shared declarations.

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.

This should allow for more efficient SIMD.
Keep the C versions as they are now, to allow the compiler to inline the

hevc: Remove useless clip
...
The src buffer should only contain values in the interval
[0, (1 << BIT_DEPTH) - 1].
Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in
the interval [0, 31], so no clip is needed.

The reconstructed picture should always be clipped (see section 8.6.5),
previously we did not clip coding units where
cu_transquant_bypass_flag == 1.
