- SchemaItem, SchemaType now descend from common type

SchemaEventTarget, which supplies dispatch
- the dispatch now provides before_parent_attach(),
after_parent_attach(), events which generally bound the _set_parent()
event. [ticket:2037]
- the _on_table_attach mechanism now usually uses the
event dispatch
- fixed class-level event dispatch to propagate to all subclasses, not just
immediate subclasses
- fixed class-level event unpickling to handle more involved
inheritance hierarchies, needed by the new schema event dispatch.
- ForeignKeyConstraint doesn't re-call the column attach event
on ForeignKey objects that are already associated with the correct
Column
- we still need that ImportError on mysqldb CLIENT FLAGS to support
mock DBAPIs
