Snapshot creation and restoration (#1679) * to_rlp takes self by-reference * clean up some derefs * out-of-order insertion for blockchain * implement block rebuilder without verification * group block chunk header into struct * block rebuilder does verification * integrate snapshot service with client service; flesh out implementation more * initial implementation of snapshot service * remove snapshottaker trait * snapshot writer trait with packed and loose implementations * write chunks using "snapshotwriter" in service * have snapshot taking use snapshotwriter * implement snapshot readers * back up client dbs when replacing * use snapshot reader in snapshot service * describe offset format * use new get_db_path in parity, allow some errors in service * blockchain formatting * implement parity snapshot * implement snapshot restore * force blocks to be submitted in order * fix bug loading block hashes in packed reader * fix seal field loading * fix uncle hash computation * fix a few bugs * store genesis state in db. reverse block chunk order in packed writer * allow out-of-order import for blocks * bring restoration types together * only snapshot the last 30000 blocks * restore into overlaydb instead of journaldb * commit version to database * use memorydbs and commit directly * fix trie test compilation * fix failing tests * sha3_null_rlp, not H256::zero * move overlaydb to ref_overlaydb, add new overlaydb without on-disk rc * port archivedb to new overlaydb * add deletion mode tests for overlaydb * use new overlaydb, check state root at end * share chain info between state and block snapshotting * create blocks snapshot using blockchain directly * allow snapshot from arbitrary block, remove panickers from snapshot creation * begin test framework * blockchain chunking test * implement stateproducer::tick * state snapshot test * create block and state chunks concurrently, better restoration informant * fix tests * add deletion mode tests for overlaydb * address comments * more tests * Fix up tests. * remove a few printlns * add a little more documentation to `commit` * fix tests * fix ref_overlaydb test names * snapshot command skeleton * revert ref_overlaydb renaming * reimplement snapshot commands * fix many errors * everything but inject * get ethcore compiling * get snapshot tests passing again * instrument snapshot commands again * fix fallout from other changes, mark snapshots as experimental * optimize injection patterns * do two injections * fix up tests * take snapshots from 1000 blocks efore * address minor comments * fix a few io crate related errors * clarify names about total difficulty [ci skip]
