Sync OpenBSD patchset 345:
Don't attempt to open() the tty path, rely on the client sending its stdin fd
with imsg and fatal if it doesn't, then set the FD_CLOEXEC flag in tty_init
instead of tty_open to prevent them leaking into child processes if any are
created between the two calls.
This bumps the protocol version, so the tmux server should be killed before
upgrading.
