tty: Add option to forward unrequested escape sequence

Browse Source 
Adds an option "forward-unrequested-escseq" for tmux to forward
unrequested escape sequences to the client. For example, when an OSC 52
escape sequence is received outside a designated TTY_OSC52QUERY context,
it will be passed on to the client application if the option is on,
otherwise it's discarded.
