Expose some mdbx statistics/metadata to ruby. - Add anonymous structs for settings and state to the internal db instance struct. - Allow tweaking the max_readers setting on db open. - Allow altering database sizing/geometry values. - Start sketching out some transaction re-entrancy. - Refactor initialization slightly, just use the db struct instead of additional unnecessary vars.
