  Fix for fix bug#12922.


sql/item.cc:
  Fix for fix bug#12922.

Any form of HANDLER statement is forbidden from usage in stored procedures/functions.


mysql-test/r/sp-error.result:
  Results for the test case for Bug#12995 added.
mysql-test/t/sp-error.test:
  Test case for Bug#12995 added.
sql/sql_yacc.yy:
  Forbid any form of "HANDLER" statement from use in stored procedures/functions.

Fields of view represented by Item_direct_view_ref. When complex expression
such as if(sum()>...,...) is splited in simpler parts by refs was ignored.
Beside this direct ref doesn't use it's result_field and thus can't store
it's result in tmp table which is needed for sum() ... group.
All this results in reported bug.

Item::split_sum_func2() now converts Item_direct_view_ref to Item_ref to
make fields from view being storable in tmp table.


sql/item.h:
  Fix bug #12922 if(sum(),...) with group from view returns wrong results
  Added function ref_type() to distinguish Item_ref subclasses

Small tweak for random read performance (we shouldn't always tell the OS that we will be doing a linear scan).
