Select full-pel search method based on quantizer

For speed 1 and 2, full pixel motion search method is selected based on
the frame quantizer and resolution. Two new search methods are
introduced, NSTEP_8PT and CLAMPED_DIAMOND. The search is made more
aggressive for high quantizers, and the search window is reduced for
lower resolutions at high quantizers.
