Comparison of a BIGINT NOT NULL column with a constant arithmetic
expression that evaluates to NULL caused error 1048: "Column '...'
cannot be null".

Made convert_constant_item() check if the constant expression is NULL
before attempting to store it in a field. Attempts to store NULL in a
NOT NULL field caused query errors.


sql/item_cmpfunc.cc:
  Fixed bug #32335.
  1. Made convert_constant_item() check if the constant expression is NULL
     before attempting to store it in a field. Attempts to store NULL in
     a NOT NULL field caused query errors.
  
  2. Also minor bug has been fixed: the thd->count_cuted_fields value
     was not restored in case of successful conversion.

  Added test case for bug #32335.

The problem was in incorrectly calculated length of the buffer used to
store a hexadecimal representation of an index map in
select_describe(). This could result in buffer overrun and stack
corruption under some circumstances.

Fixed by correcting the calculation.

storage engine system variables was not validated and
unexpected value was assigned.

The check_func_enum function used subtraction from the uint
value with the probably negative result. That result of
type uint was compared with 0 after casting to signed long
type. On architectures where long type is longer than int
type the result of comparison was unexpected.
