Bug#10418: LOAD_FILE does not behave like in manual if file does not exist
load_file() string-function should return NULL rather than throw an error if the file doesn't exist, as per the manual. mysql-test/t/outfile.test: expect NULL rather than error if file given to load_file() doesn't exist mysql-test/t/func_str.test: show that load_file() will return NULL rather than throw an error if file doesn't exist mysql-test/r/outfile.result: expect NULL rather than error if file given to load_file() doesn't exist mysql-test/r/func_str.result: expect NULL rather than error if file given to load_file() doesn't exist sql/item_strfunc.cc: load_file() should return NULL as per the docs if file not found, rather than throw an error
