the UDF
When deleting a user defined function MySQL must remove it from both the
in-memory hash table and the mysql.proc system table.
Finding (and removal therefore) from the internal hash table is case
insensitive (or whatever the default charset is), whereas finding and
removal from the system table is case sensitive.
As a result if you supply a function name that is not in the same character
case to DROP FUNCTION the server will remove the function only from the
in-memory hash table and will keep the row in mysql.proc system table.
This will cause inconsistency between the two structures (that is fixed
only by restarting the server).
Fixed by using the name in the precise case (from the in-memory hash table)
to delete the row in the mysql.proc system table.

Problem:
When creating a temporary field for a temporary table in create_tmp_field_from_field(), a resulting field is created as an exact copy of an original one (in Field::new_field()). However, Field_enum and Field_set contain a pointer (typelib) to memory allocated in the parent table's MEM_ROOT, which under some circumstances may be deallocated later by the time a temporary table is used.
Solution:
Override the new_field() method for Field_enum and Field_set and create a separate copy of the typelib structure in there.
include/typelib.h:
Added copy_typelib() declaration
mysql-test/r/sp.result:
Added a testcase for bug #24117 "server crash on a FETCH with a cursor on a table which is not in the table cache"
mysql-test/t/sp.test:
Added a testcase for bug #24117 "server crash on a FETCH with a cursor on a table which is not in the table cache"
mysys/typelib.c:
Added copy_typelib() definition
sql/field.cc:
Create a copy of the internal 'typelib' structure when copying Field_enum of Field_set objects.
sql/field.h:
Override new_field method in Field_enum (and Field_set) to copy the typelib structure.

Fixed bug #24670: optimizations that are legal only for subqueries without tables
and no WHERE condition were applied for any subquery without tables.
Removed an assertion that caused an abort for subqueries without tables and no
WHERE condition.
Blocked substitution of a single-row subquery without tables for the constant
row from its select list when the subquery contained a WHERE condition.
This optimization is valid only for subquries without tables with no conditions.
Any subquery without tables with WHERE clause returns NULL if the WHERE condition
is FALSE. Erroneously it was always considered as non-nullable that could trigger
another optimization concerning IS NULL predicates which is applicable only for
non-nullable expressions and ultimately led to a wrong result returned by the outer
query.
Added a proper implementation of the virtual method may_be_null for class
subselect_single_select_engine.
sql/item_subselect.h:
Fixed bug #24670: optimizations that are legal only for subqueries without tables
and no WHERE condition were applied for any subquery without tables.
Made method may_by_null for class subselect_engine vvirtual.
