for now - fix up adaptation tests to still try to exercise the correlation argument
so it can be managed more easily
- update "not supported" messages for empty inserts, mutlivalue inserts - rework the ValuesBase approach for multiple value sets so that stmt.parameters does store a list for multiple values; the _has_multiple_parameters flag now indicates which of the two modes the statement is within. it now raises exceptions if a subsequent call to values() attempts to call a ValuesBase with one mode in the style of the other mode; that is, you can't switch a single- or multi- valued ValuesBase to the other mode, and also if a multiple value is passed simultaneously with a kwargs set. Added tests for these error conditions - Calling values() multiple times in multivalue mode now extends the parameter list to include the new parameter sets. - add error/test if multiple *args were passed to ValuesBase.values() - rework the compiler approach for multivalue inserts, back to where _get_colparams() returns the same list of (column, value) as before, thereby maintaining the identical number of append() and other calls when multivalue is not enabled. In the case of multivalue, it makes a last-minute switch to return a list of lists instead of the single list. As it constructs the additional lists, the inline defaults and other calculated default parameters of the first parameter set are copied into the newly generated lists so that these features continue to function for a multivalue insert. Multivalue inserts now add no additional function calls to the compilation for regular insert constructs. - parameter lists for multivalue inserts now includes an integer index for all parameter sets. - add detailed documentation for ValuesBase.values(), including careful wording to describe the difference between multiple values and an executemany() call. - add a test for multivalue insert + returning - it works ! - remove the very old/never used "postgresql_returning"/"firebird_returning" flags.
cutting up tests and removing old ones - move test_in() to test_operators - slice up migrated operator tests into TOT

become an externally usable package but still remains within the main sqlalchemy parent package. in this system, we use kind of an ugly hack to get the noseplugin imported outside of the "sqlalchemy" package, while still making it available within sqlalchemy for usage by third party libraries.
- resolved some serious speed hits I missed, we need to ensure only deannotated columns are used in the local/remote collections and soforth so that hash lookups against mapped columns don't dig into __eq__() - fix some other parity mismatches regarding stuff from [ticket:2453], including finding another case where _deep_annotate() was doing the wrong thing, new tests. - [feature] Major rewrite of relationship() internals now allow join conditions which include columns pointing to themselves within composite foreign keys. A new API for very specialized primaryjoin conditions is added, allowing conditions based on SQL functions, CAST, etc. to be handled by placing the annotation functions remote() and foreign() inline within the expression when necessary. Previous recipes using the semi-private _local_remote_pairs approach can be upgraded to this new approach. [ticket:1401]
in the corresponding selectable to take into account clones of the target column. fixes [ticket:2419] - have _make_proxy() copy out the _is_clone_of attribute on the new column so that even more corresponding_column() checks work as expected for cloned elements. - add a new test fixture so that mapped tests can be specified using declarative.
