Sergey Glukhov 5f9e40a5f8 Bug#44358 valgrind errors with decode() function
The warning happens because string argument is not zero ended.
The fix is to add new parameter 'length' to SQL_CRYPT() and
use ptr() instead of c_ptr().


mysql-test/r/func_str.result:
  test result
mysql-test/t/func_str.test:
  test case
sql/item_strfunc.cc:
  Added new parameter 'length' to SQL_CRYPT
sql/sql_crypt.cc:
  Added new parameter 'length' to SQL_CRYPT
sql/sql_crypt.h:
  Added new parameter 'length' to SQL_CRYPT
