Fix fragment output variables validation

* Reject fragment shaders that assign
  out-of-range fragment locations

* Reject fragment shaders that assign
  output variables of different types
  to the same location

* Apply similar validation for fragment
  outputs bound via API calls

* Ensure that masks for active output
  variables and draw buffer types are
  set after processing all fragment
  output bindings
