speedsup p2p sync

A new object to control state of syncig added. There are 3 state of sync: p2p, reindex and live. P2P and REINDEX sync used the same massive dumper of blocks to database, but the have different triggers -> P2P dumps at least 1000 blocks but all of them must be considered by node as irreversible, REINDEX unconditionally dumps packages of 1000 of blocks because a block_log contains only irreversible blocks. LIVE sync uses llive dumper, and dumps blocks one by one with calling 'hive.push_block' hive fork manager function.
