* optimize addProposalBlockPart * optimize addProposalBlockPart * if ProposalBlockParts and LockedBlockParts both exist,let LockedBlockParts overwrite ProposalBlockParts. * fix tryAddBlock * broadcast lockedBlockParts in higher priority * when appHeight==0, it's better fetch genDoc than state.validators. * not save state if replay from height 1 * only save state if replay from height 1 when stateHeight is also 1 * only save state if replay from height 1 when stateHeight is also 1 * only save state if replay from height 0 when stateHeight is also 0 * handshake info's response version only update when stateHeight==0 * save the handshake responseInfo appVersion
