Add support for fortify source level 2 to strncpy. This will enable detection of more areas where strncpy is used inappropriately. For example, this would have detected bug 8727221. Move the fortify_source tests out of string_test.cpp, and put it into fortify1_test.cpp. Create a new fortify2_test.cpp file, which copies all the tests in fortify1_test.cpp, and adds fortify_source level 2 specific tests.
