This commit re-structures the speed feature setup for the codec development purpose. Instead of progressively reducing encoder complexity at the expense of incremental coding loss, we allow a separate set of speed features, each corresponds to a certain category of coding units: 1 << 0: transform coding 1 << 1: inter prediction 1 << 2: intra prediction 1 << 3: block partition 1 << 4: loop filters 1 << 5: rd early skip [6 - 7] are left open for next adjustment. It is constructed to facilitate the codec development purpose. When working on a coding functions, one could choose to turn on one or more less related coding units to speed up the evaluation process. For example, to test a transform related experiment, one could set --dev-sf=2, 6, or 22 which corresponds to turning on: 2 - inter prediction speed features, 6 - both inter / intra speed features, 22 - inter / intra, and loop filter features. The goal is to allow faster experimental verification during the development process. With the experiment in a stable state, we can evaluate its performance in speed 0 at higher confidence level.
