Add a per-client log of status line messages displayed while that client

exists. A new message-limit session option sets the maximum number of entries
and a command, show-messages, shows the log (bound to ~ by default).

This (and prompt history) might be better as a single global log but until
there are global options it is easier for them to be per client.
