Test the mmap() flag, and the mlockall() flag. These tests ensure that pages are not faulted in until they are accessed, that the pages are unevictable once faulted in, and that VMA splitting and merging works with the new VM flag. The second test ensures that mlock limits are respected. Note that the limit test needs to be run a normal user. Also add tests to use the new mlock2 family of system calls.
