array.__init__() expects a list as its sole parameter but inside _bind_param(), instead of sending a list it's sending each item in the list as a separate argument which is incorrect.

- add support for IDENTITY INSERT setting for INSERT with inline VALUES

- be specific as to what occurred when we collect stray gc

where engine-level isolation level parameter would raise an error
on connect. fixes #3134

- edit strategies.py to conform

the "outer join" propagation along a chain of joined eager loads
would incorrectly convert an "inner join" along a sibling join path
into an outer join as well, when only descendant paths should be
receiving the "outer join" propagation; additionally, fixed related
issue where "nested" join propagation would take place inappropriately
between two sibling join paths.

this is accomplished by re-introducing the removed flag "allow_innerjoin",
now inverted and named "chained_from_outerjoin".  Propagating this flag
allows us to know when we have encountered an outerjoin along a load
path, without confusing it for state obtained from a sibling path.
