c87187f913 When changing so that the client passes its stdout and stderr as well as 
stdin up to the server, I forgot one essential point - the tmux server
could now be both the producer and consumer. This happens when tmux is
run inside tmux, as well as when piping tmux commands together.

So, using stdio(3) was a bad idea - if sufficient data was written, this
could block in write(2). When that happened and the server was both
producer and consumer, it deadlocks.

Change to use libevent bufferevents for the client stdin, stdout and
stderr instead. This is trivial enough for output but requires a
callback mechanism to trigger when stdin is finished.

This relies on the underlying polling mechanism for libevent to work
with whatever devices to which the user could redirect stdin, stdout or
stderr, hence the change to use poll(2) over kqueue(2) for tmux.

bf09b00fe9 kqueue(2) is currently broken when used with /dev/null and a few other 
devices.

An upcoming fix for some problems with the client stdout/stderr handling
relies on it working, so make tmux force libevent to use poll(2) via
EVENT_NOKQUEUE, until we have fixed kqueue.

a97b7ad11c Fix a crash: if remain-on-exit is set and the pane has exited, the 
buffers may not be valid, so do not try to disable/enable them when
switching to copy mode.

2b80ede963 Don't return if in the current window since we may want to report a bell 
(if bell-action any/current), just clear the flag so the status line
doesn't show the bell.

b9c873cdaa Return the command client return code with MSG_EXIT now that MSG_ERROR and 
MSG_PRINT are unused.

New clients should be compatible with old tmux servers but vice versa may print
an error.

552c9cd83f Custom layouts. list-windows command displays the layout as a string (such as 
"bb62,159x48,0,0{79x48,0,0,79x48,80,0}") and it can be applied to another
window (with the same number of panes or fewer) using select-layout.

76bbdeb586 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).

42e2413978 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.

510ec3fb9e 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.

43fa9a9ba6 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).

4f5c5b37b8 Pass in the session, rather than the client, to window modes' key() 
function. We were only ever using the client to find the session anyway.

This allows send-key to work properly for manipulating copy mode from
outside tmux.
