Clean ups of the subpel search functions Removes some unused code and speed features, and organizes the interfaces for fractional mv step functions for use in new speed features to come. In the process a new speed feature - number of iterations per step during the subpel search - is exposed. No change when this parameter is set as the original value of 3. Results: subpel_iters_per_step = 3: baseline subpel_iters_per_step = 2: psnr -0.067%, 1% speedup subpel_iters_per_step = 1: psnr -0.331%, 3-4% speedup Change-Id: I2eba8a21f6461be8caf56af04a5337257a5693a8
