Post-review fixes for bug #1790 'BIT_AND() result in GROUP BY different when

 SQL_BIG_RESULT used':
- BIT_AND now returns BIGINT UNSIGNED
- in case there were no matching rows BIT_AND returns 18446744073709551615 
(but not NULL), BIT_OR returns 0 (but not NULL). That's how Monty wants it
and how is described in our docs.




include/my_global.h:
  Added definition for ULONGLONG_MAX.
  This is also a check that ULL type specifier
  can be used on all supported platforms.
