Adds a stand-alone resize_util app for testing. The app
will not be built in the shared library configurations
so as not to require the APIs to be exposed.

Adds multiple filters in the 0.5-1.0 range in the last stage
of the resize functions to prevent over-smoothing/aliasing

This avoids fitlering a frame multiple times at the same level.

Change-Id: I1fd54dd7ea257d16da8569f48036b8fad3a3ed61

Factor out the code that tries filtering a frame at a given level.

We don't use different filter kernels for x and y, it is always one kernel
for both directions.

SSE for a 64x64 block with 3 planes can go as high as 3*2^28. So left
shift by 4 may overflow 32 bit int.

Use this method with rt at speed -5.

The sum of squared mv components can go beyond int range for large
 input resolution. This commit changed the type to int64 to avoid
overflow.

New API is supposed to be used from example code. Current implementation
only supports IVF containers (will be extended to Y4M).
