Stop using database (and including database.hh) for schema related purposes and use data_dictionary instead. data_dictionary::database::real_database() is called from several places, for these reasons: - calling yet-to-be-converted code - callers with a legitimate need to access data (e.g. system_keyspace) but with the ::database accessor removed from query_processor. We'll need to find another way to supply system_keyspace with data access. - to gain access to the wasm engine for testing whether used defined functions compile. We'll have to find another way to do this as well. The change is a straightforward replacement. One case in modification_statement had to change a capture, but everything else was just a search-and-replace. Some files that lost "database.hh" gained "mutation.hh", which they previously had access to through "database.hh".
