With this patch, and the speed settings turned on for speed 1, the coding efficiency of speed 1 in default configuration should be only a little worse than speed 0, but it should roughly run at double the speed. Specifically, this patch makes various changes to make sure that speed 1 behaves exactly the same as speed 0 except for speed settings turned on or off in speed_features.c. This will change the bitstream generated a little for speeds 1 or higher because of the following reasons: 1. Removes a hacky speed setting correction factor in firstpass.c 2. Fast cdef search is moved from speed 1+ to 2+, and a new speed feature is added to control that. 3. Mesh search settings are pushed down one level so that speeds 0 and 1 use the same settings. 4. A disable_split_mask feature for animated content previously turned on speeds 1+ is moved down to speeds 2+. Change-Id: I0ec36556f157bdc42c5daa0cfb9518cf7ff65f6b
