On execwm, we should properly release resources before exec'ing into a

new window manager; so allow CWM_EXEC_WM to assign new wm to wm_argv and
pass through cwm_status (now EXECWM) so that x_teardown() gets called
before exec'ing the new window manager.  Removes the need for a separate
x_restart() now, using new wm_argv; and consolidates errno for execvp.
