Update block headers to include multiple levels of parent blocks (#1822)
* Replace the old parents in the block header with BlockLevelParents. * Begin fixing compilation errors. * Implement database serialization for block level parents. * Implement p2p serialization for block level parents. * Implement rpc serialization for block level parents. * Add DirectParents() to the block header interface. * Use DirectParents() instead of Parents() in some places. * Revert test_block_builder.go. * Add block level parents to hash serialization. * Use the zero hash for genesis finality points. * Fix failing tests. * Fix a variable name. * Update headerEstimatedSerializedSize. * Add comments in blocklevelparents.go. * Fix the rpc-stability stability test. * Change the field number for `parents` fields in p2p.proto and rpc.proto. * Remove MsgBlockHeader::NumParentBlocks.
