* refs/heads/master: Only when mapping clients from an initial wm start or restart, query the pointer and if it matches the child window, activate it; new clients will not need to make this roundtrip to the server. 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.
