Various refactoring to make the subpel motion compensation filters switchable by a frame level field. Two types of 8-tap filters are supported in addition to the existing bilinar and sixtap filters. One is the default 8-tap and the other has a sharper cut-off for use with frames with substantial edge content. Patch 2: Added a preliminary strategy for filter selection based on edginess detecton. Also includes some filter changes. Change-Id: I866085bda5ae143cfdf2ec88157feaabdf7bd63a
