Jun Wu 225a0771b4 treestate: revise StateFlags bits ... Summary: The "added", "removed", "normal", "? (untracked)" 4 states could be simplified to 2 bits: "EXIST_P1", "EXIST_NEXT". With "merge" considered, adding "EXIST_P2" would be enough. This avoids some invalid states, making it easier to reason about. It also makes Mercurial dirstate hacks like size = -1, size = -2 noting "merge" and "otherparent" unnecessary. With this change, the previous `state_required_all`, `state_required_any` query parameters are not powerful enough. That would be changed to functions in a later diff. There is a new need to select files by querying "unset" bits. That will be addressed by D7886281.
