Sync OpenBSD patchset 347:
Remove the internal tmux locking and instead detach each client and run the command specified by a new option "lock-command" (by default "lock -np") in each client. This means each terminal has to be unlocked individually but simplifies the code and allows the system password to be used to unlock. Note that the set-password command is gone, so it will need to be removed from configuration files, and the -U command line flag has been removed. This is the third protocol version change so again it is best to stop the tmux server before upgrading.
