Bug#36086: SELECT * from views don't check column grants

This patch also fixes bugs 36963 and 35600.
                      
- In many places a view was confused with an anonymous derived
  table, i.e. access checking was skipped. Fixed by introducing a
  predicate to tell the difference between named and anonymous
  derived tables.
                      
- When inserting fields for "SELECT * ", there was no 
  distinction between base tables and views, where one should be
  made. View privileges are checked elsewhere.
