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".
Seastar moved the read_entire_stream(), read_entire_stream_contiguous()
and skip_entire_stream() from the "httpd" namespace to the "util"
namespace. Using them with their old names causes deprecation warnings
when compiling alternator/server.cc.
This patch fixes the namespace (and adds the new include) to get rid of
the deprecation warnings.

Throw a proper exception from do_load_schemas if parse_statements
fails to parse the schema cql.
Catch it in scylla-sstable main() function so
it won't be reported as seastar - unhandled exception.

Serialize the metadata changes with
keyspace create, update, or drop.
This will become necessary in the following patch
when we update the effective_replication_map
on all keyspaces and we want instances on all shards
end up with the same replication map.
Note that storage_service::keyspace_changed is called
from the scheme_merge path so it already holds
the merge_lock.

A utility which can load a schema from a schema.cql file. The file has
to contain all the "dependencies" of the table: keyspace, UDTs, etc.
This will be used by the scylla-sstable-crawler in the next patch.
