fix for bug #1790:
"BIT_AND() result in GROUP BY different when SQL_BIG_RESULT used"
return value of BIT_AND changed to BIGINT SIGNED
Also the patch fixes another bug: when temporary table is in use and one of
values in group is NULL, BIT_AND always returns zero.
Fixed it to always skip null values.
mysql-test/r/func_group.result:
bug #1790: test results fixed
sql/item_sum.cc:
fix for bug #1790:
update_field() rewritten to use add() and thus was moved
to Item_sum_bit::update_field()
Item_sum_bit::reset_field() was rewritten to take into account
reset_bits.
sql/item_sum.h:
fix for bug #1790:
Item_sum::update_field() and Item_sum::reset_field() commented
Item_sum_and changed to return BIGINT SIGNED
Item_sum_and::update_field() and Item_sum_or::update_field)
were replaced with generic Item_sum_bit::update_field()
