made the check for recursion overflow in self-referential
eager joining too loose, missing a particular circumstance
where a subclass had lazy="joined" or "subquery" configured
and the load was a "with_polymorphic" against the base.

regards to the True/False constants. An expression like
``col.is_(True)`` will now render ``col IS true``
on the target platform, rather than converting the True/
False constant to an integer bound parameter.
This allows the ``is_()`` operator to work on MySQL when
given True/False constants.

input types of sets, generators, etc. but only when a dimension
is specified for the ARRAY; otherwise, the dialect
needs to peek inside of "arr[0]" to guess how many
dimensions are in use. If this occurs with a non
list/tuple type, the error message is now informative
and directs to specify a dimension for the ARRAY.

the creation of strong references within the Session;
an object will no longer have an internal reference cycle
created if it's in the transient state or moves into the
detached state - the strong ref is created only when the
object is attached to a Session and is removed when the
object is detached. This makes it somewhat safer for an
object to have a `__del__()` method, even though this is
not recommended, as relationships with backrefs produce
cycles too. A warning has been added when a class with
a `__del__()` method is mapped.

- Part of a longer series of fixes needed for pyodbc+
mssql, a CAST to NVARCHAR(max) has been added to the bound
parameter for the table name and schema name in all information schema
queries to avoid the issue of comparing NVARCHAR to NTEXT,
which seems to be rejected by the ODBC driver in some cases,
such as FreeTDS (0.91 only?) plus unicode bound parameters being passed.
The issue seems to be specific to the SQL Server information
schema tables and the workaround is harmless for those cases
where the problem doesn't exist in the first place.

handling. If a non-disconnect error occurs,
but leads to a delayed disconnect error within error
handling (happens with MySQL), the disconnect condition
is detected. The Connection can now also be closed
when in an invalid state, meaning it will raise "closed"
on next usage, and additionally the "close with result"
feature will work even if the autorollback in an error
handling routine fails and regardless of whether the
condition is a disconnect or not.

labeled columns when apply_labels() is used; this mode
produces a SELECT where each column is labeled as in
<tablename>_<columnname>, to remove column name collisions
for a multiple table select. The fix is that if two labels
collide when combined with the table name, i.e.
"foo.bar_id" and "foo_bar.id", anonymous aliasing will be
applied to one of the dupes. This allows the ORM to handle
both columns independently; previously, 0.7
would in some cases silently emit a second SELECT for the
column that was "duped", and in 0.8 an ambiguous column error
would be emitted. The "keys" applied to the .c. collection
of the select() will also be deduped, so that the "column
being replaced" warning will no longer emit for any select()
that specifies use_labels, though the dupe key will be given
an anonymous label which isn't generally user-friendly.

where since it considers the current class' ``__table__``, was
sensitive to when it was called. This is 0.7's behavior also,
but in 0.7 things tended to "work out" within events like
``__mapper_args__()``. :func:`.has_inherited_table` now only
considers superclasses, so should return the same answer
regarding the current class no matter when it's called
(obviously assuming the state of the superclass).

``query(SubClass).options(subqueryload(Baseclass.attrname))``,
where ``SubClass`` is a joined inh of ``BaseClass``,
would fail to apply the ``JOIN`` inside the subquery
on the attribute load, producing a cartesian product.
The populated results still tended to be correct as additional
rows are just ignored, so this issue may be present as a
performance degradation in applications that are
otherwise working correctly. [ticket:2699]
