Bug#57257 Replace(ExtractValue(...)) causes MySQL crash
Bug#57820 extractvalue crashes
Problem: ExtractValue and Replace crashed in some cases
due to invalid handling of empty and NULL arguments.
Per file comments:
@mysql-test/r/ctype_ujis.result
@mysql-test/r/xml.result
@mysql-test/t/ctype_ujis.test
@mysql-test/t/xml.test
Adding tests
@sql/item_strfunc.cc
Make sure Item_func_replace::val_str safely handles empty strings.
@sql/item_xmlfunc.cc
set null_value if nodeset_func returned NULL,
which is possible when the second argument is an
unset user variable.
