Bug#21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.
Variable character_set_results can legally be NULL (for "no conversion.")
This could result in a NULL deref that crashed the server. Fixed.
(Although ran some additional precursory tests to see whether I could break
anything else, but no breakage so far.)

Bug#21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.
Prove DATE_FORMAT() no longer crashes the server when character_set_results is
NULL (which is a legal value and means, "no conversion").

Bug#21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.
Avoid NULL deref in my_charset_same() -- if !to_cs, we won't need to compare
because it is magic for, "no conversion."
