Sync OpenBSD patchset 1138:

Add a skeleton mode to tmux (called "control mode") that let's tmux
commands be sent and output received on stdout. This can be used to
integrate with other terminal emulators and should allow some other
things to be made simpler later. More to come so doesn't do much yet and
deliberately not documented.
