fully implement future engine and remove legacy
The major action here is to lift and move future.Connection
and future.Engine fully into sqlalchemy.engine.base. This
removes lots of engine concepts, including:
* autocommit
* Connection running without a transaction, autobegin
is now present in all cases
* most "autorollback" is obsolete
* Core-level subtransactions (i.e. MarkerTransaction)
* "branched" connections, copies of connections
* execution_options() returns self, not a new connection
* old argument formats, distill_params(), simplifies calling
scheme between engine methods
* before/after_execute() events (oriented towards compiled constructs)
don't emit for exec_driver_sql(). before/after_cursor_execute()
is still included for this
* old helper methods superseded by context managers, connection.transaction(),
engine.transaction() engine.run_callable()
* ancient engine-level reflection methods has_table(), table_names()
* sqlalchemy.testing.engines.proxying_engine
