f731ae4a2d Revert use of DECSLRM on iTerm2, it doesn't help as much as we throught, 
and there are some question marks about it's support.

8c8ce08d79 On terminals without DECSLRM, when a pane that is less than the full 
with of the terminal scrolls, tmux needs to redraw the entire pane. This
results in a large amount of output data which can cause slow terminals
to struggle, particularly when many lines are scrolled together quickly.

This can be reduced by only redrawing when tmux doesn't hold any
buffered data for the terminal. If a redraw is required and data is
buffered, the redraw is deferred until all that data is consumed (it is
checked after every event loop, a timer is used to ensure this happens
at some point). While a redraw is pending, no additional data will be
written to the terminal.

The redraw still happens, now it is just pushed back if it is possible
it would just add more data on top of a terminal that is already
behind. This both gives the terminal a chance to catch up, and allows
tmux to process more scrolling (that would require additional redraws)
in the meantime.

Helps with a problem reported by Greg Hurrell.

36882ec789 Try again to resolve problems with mistaking sessions for windows: now 
do not look up windows as sessions (and panes as windows) when they are
qualified with a ':' or a '.'. So 'foo' as a window target will look for
windows and sessions called 'foo', but ':foo' will only look for
windows, and 'foo:' only for sessions. This means the common case of
using an unadorned session as a window target (send -tfoo) should
continue to work, but an explicit window will not get confused with a
session (send -t:foo).

9b28200578 Give each client a name. This defaults to the tty name as before but 
falls back to an alternative if the tty name is not available. This is
clearer than overloading the client ttyname member and allows us to
remove the path stored in the tty struct, it should always be the same
as the client.

3c3c08b6d9 Try to avoid moving the cursor to the start of the next line when 
printing cells if it is already at the very end of the line and the
terminal will wrap it to the next line itself, this means terminals
still see it as a wrapped line for the purposes of their own mouse
selection. Reported by millert@.
