This patch only works if the video is a width and height that are both
a multiple of 32..   It sets every partition to 16x16, and does INTRADC
only on the first frame and ZEROMV on every other frame.   It always does
does the largest possible transform, and loop filter level is set to 4.

Was ~20% faster than speed -5 of vp8

Now 20% slower but adds motion search ( every block ), nearest, near
and zeromv

The SVC test was changed because - while this realtime mode produces
bad quality albeit quickly, it isn't obeying all the rules it should
about which frames are available.

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.

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).
