Change the existing client flags for control mode to apply for any client, use

the same mechanism for the read-only flag and add an ignore-size flag.

refresh-client -F has become -f (-F stays for backwards compatibility) and
attach-session and switch-client now have -f flags also. A new format
"client_flags" lists the flags and is shown by list-clients by default.

This separates the read-only flag from "ignore size" behaviour (new
ignore-size) flag - both behaviours are useful in different circumstances.

attach -r and switchc -r remain and set or toggle both flags together.
