- introduce an optimizing type _NativeUnicodeMixin to oracle plus supporting
changes to Enum/SchemaType to re-support adaptation of string types.
This approach can be adapted by "conditional" unicode returning dialects
(i.e. pyodbc and possibly mxodbc) to remove the overhead
of isinstance(value, unicode) calls when the dialect returned type is
of dbapi.UNICODE, dbapi.NVARCHAR, etc.

add a third state to converts_unicode_strings - "conditional". at the moment
this will have us do a check. i.e. for MSSQL where NVARCHAR is unicode and VARCHAR is not.

that's what you'll get. Note that the generic types.Date

however. When reflecting a table, the reflected type

- moved the logic within _BindParamClause which decides about coercing the bind's type
based on the compared type into AbstractType. The new method is called _coerce_compared_value()
and receives the operator and the raw python value to be coerced. TypeDecorator
overrides this to provude the "old" 0.5 behavior of coercing the other side of the expression
unconditonally.
- added docs to TypeDecorator attempting to explain this though they are a little verbose.
- added caveats to Interval, which in "non-native" mode can't really handle proper expression behavior. the "typing" would have to move into the compiler, such that on a DB like SQLite we're actually wrapping left/right side into its epoch functions, etc., its a big job. current infrastructure, as powerful as it is, still isn't at that level.

- orm: Removed a lot of logging that nobody really cares about,
logging that remains will respond to live changes in the
log level. No significant overhead is added. [ticket:1719]

more often, so that changes to the log level for engine/pool
will be reflected on next connect. This adds a small
amount of method call overhead. It's negligible and will make
life a lot easier for all those situations when logging
just happens to be configured after create_engine() is called.
