1. Fix issue apache#876 - column reference "_age_default_alias_0" is amb… …

   …iguous
   
   - The problem was with get_next_default_alias function which was not
     generating unique aliases.
   - Every clause transformed as a subquery has its own cpstate which is
     being freed after it is tranformed. The root cpstate is the one that
     has the default_alias_number initialized. So we need to reach the
     root cpstate to get the next correct default alias number.
   - This change also fixed some previously incorrect results.
   - Added additional regression tests.
