- merged -r4458:4466 of query_columns branch

- this branch changes query.values() to immediately return an iterator, adds a new "aliased" construct which will be the primary method to get at aliased columns when using values()
- tentative ORM versions of _join and _outerjoin are not yet public, would like to integrate with Query better (work continues in the branch)
- lots of fixes to expressions regarding cloning and correlation.  Some apparent ORM bug-workarounds removed.
- to fix a recursion issue with anonymous identifiers, bind parameters generated against columns now just use the name of the column instead of the tablename_columnname label (plus the unique integer counter).  this way expensive recursive schemes aren't needed for the anon identifier logic.   This, as usual, impacted a ton of compiler unit tests which needed a search-n-replace for the new bind names.
