pep-484: sqlalchemy.sql pass one
sqlalchemy.sql will require many passes to get all
modules even gradually typed. Will have to pick and
choose what modules can be strictly typed vs. which
can be gradual.
in this patch, emphasis is on visitors.py, cache_key.py,
annotations.py for strict typing, compiler.py is on gradual
typing but has much more structure, in particular where it
connects with the outside world.
The work within compiler.py also reached back out to
engine/cursor.py , default.py quite a bit.
