Bloomchain (#1014) * use bloomchain crate in blockchain module. remove obsole chainfilter submodule * update database version to 6.0 * removed redundant line * simple db migration * make migration slightly more functional * bloomchain migration * migration version is just a single unsigned integer * updated migration v6 * parity migration * db migration * removed hardcoded migration dir * replace ptr::copy with clone_from_slice, removed potential endianess problem from trace/db.rs * removed superfluous line * blockchains log blooms config is not exposed any more

//! Database migrations.
have AccountDB use address hash for uniqueness (#1533) * partially done alternate migration scheme * finish altering migration framework * migrate tests to new migration framework * address comments * remove superfluous newline [ci skip] * TempIdx -> TempIndex [ci skip] * modify account_db to work on address hash, not address * add a database migration for new accountdb * preserve first 96 bits of keys when combining * handle metadata keys in migration and preserve first 96 bits * fix comments and hash address instead of hash * different migrations based on pruning * migrations mutably borrow self * batch abstraction for migration * added missing licence headers * overlay recent v7 migration * better error handling, migrate version key as well * fix migration tests * commit final batch and migrate journaled insertions * two passes on journal to migrate all possible deleted keys
