Add string function times to wmem_test. The system, GLib, and wmem string functions can perform differently, particularly on Windows. Start adding performance tests to wmem_test so that we can see the differences. With this change applied "wmem_test --verbose" prints out the following on a Windows 7 x64 VM here. wmem_test is linked against GLib 2.4.20.
