Add tests for Safe-Linking
Adding the test "tst-safe-linking" for testing that Safe-Linking works as expected. The test checks these 3 main flows: * tcache protection * fastbin protection * malloc_consolidate() correctness As there is a random chance of 1/16 that of the alignment will remain correct, the test checks each flow up to 10 times, using different random values for the pointer corruption. As a result, the chance for a false failure of a given tested flow is 2**(-40), thus highly unlikely. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
