Fixes: #265 Initial test for membarrier() syscall. It tests all existing membarrier "commands" (or features), including the need (or not) for previous registration for the call to work. Some features did not exist in older kernels and that is covered by skipping some calls, flagging test as skipped & okay, and forcing others, making sure that return codes and errno are set right in those cases.
