Send all three of stdin, stdout, stderr from the client to the server, so that
commands can directly make use of them. This means that load-buffer and
save-buffer can have "-" as the file to read from stdin or write to stdout.
This is a protocol version bump so the tmux server will need to be restarted
after upgrade (or an older client used).
Store the current working directory in the session, change the default-path
option to default to empty and make that mean that the stored session CWD is
used.
New option, detach-on-destroy, to set what happens to a client when the session
it is attached to is destroyed. If on (the default), it is detached; if off, it
is switched to the most recently active session.
Setting the cmdlist pointer in the bind-key to NULL to prevent it being freed
after the command is executing is bogus because it may still be needed if the
same command is going to be executed again (for example if you "bind-key a
bind-key b ..."). Making a copy is hard, so instead add a reference count to
the cmd_list.
While here, also print bind-key -n and the rest of the flags properly.
Fixes problem reported by mcbride@.
Last change erroneously used the target argument for looking up the
client which caused pipe-pane to fail when used from the command
line. Instead pass NULL which should use the current client.

Fix problems with window sizing seen by Raghavendra D Prabhu when
starting tmux from .xinitrc.
One of the very few things the server relies on the client for now is to
pass through a message on SIGWINCH, but there is a condition where
potentially a SIGWINCH may be lost during the transition from unattached
(main.c) to attached (client.c). So trigger a size change immediately
after the client installs its SIGWINCH handler.
Also, when the terminal is resized, reset the scroll region and cursor
position. Previously, we were clearing our saved idea of these, but in
fact some terminals do not reset them on resize, so this caused problems
during redraw.
While here make a resize to the same size not cause a redraw and rename
the tmux.out output log file to include the tmux PID.
When the mode-mouse option is on, support dragging to make a selection
in copy mode.
Also support the scroll wheel, although xterm strangely does not ignore
it in application mouse mode, causing redraw artifacts when scrolling up
(other terminals appear to be better behaved).
