Instead of passing stdin/stdout/stderr file descriptors over imsg and
handling them in the server, handle them in the client and pass buffers
over imsg. This is much tidier for some upcoming changes and the
performance hit isn't critical.
The tty fd is still passed to the server as before.
This bumps the tmux protocol version so new clients and old servers are
incompatible.

Add a flag to move-window to renumber the windows in a session (closing

Add a simple form of output rate limiting by counting the number of
certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
exceeds a threshold (current default 50/millisecond), start to redraw
the pane every 100 milliseconds instead of making each change as it
comes. Two configuration options - c0-change-trigger and
c0-change-interval.
This makes tmux much more responsive under very fast output (for example
yes(1) or accidentally cat'ing a large file) but may not be perfect on
all terminals and connections - feedback very welcome, particularly
where this change has a negative rather than positive effect (making it
off by default is a possibility).
After much experimentation based originally on a request Robin Lee
Powell (which ended with a completely different solution), this idea

Simplify the way jobs work and drop the persist type, so all jobs are
fire-and-forget.
Status jobs now managed with two trees of output (new and old), rather
than storing the output in the jobs themselves. When the status line is
processed any jobs which don't appear in the new tree are started and
the output from the old tree displayed. When a job finishes it updates
the new tree with its output and that is used for any subsequent
redraws. When the status interval expires, the new tree is moved to the
old so that all jobs are run again.
This fixes the "#(echo %H:%M:%S)" problem which would lead to thousands
of identical persistent jobs and high memory use (this can still be
achieved by adding "sleep 30" but that is much less likely to happen by
accident).

Move all calls to fcntl(...O_NONBLOCK) into a function and clear the

Clean up and simplify tmux command argument parsing.
Originally, tmux commands were parsed in the client process into a
struct with the command data which was then serialised and sent to the
server to be executed. The parsing was later moved into the server (an
argv was sent from the client), but the parse step and intermediate
struct was kept.
This change removes that struct and the separate parse step. Argument
parsing and printing is now common to all commands (in arguments.c) with
each command left with just an optional check function (to validate the
arguments at parse time), the exec function and a function to set up any
key bindings (renamed from the old init function).
This is overall more simple and consistent.
There should be no changes to any commands behaviour or syntax although
as this touches every command please watch for any unexpected changes.
Support for UTF-8 mouse input (\033[1005h). This was added in xterm 262

same manner as the utf8 option.

Do not call event_del() for signals after fork(), just use sigaction()

Change the way backoff works. Instead of stopping reading from the pty
when the client tty backs up too much, just stop updating the tty and
only update the internal screen. Then when the tty recovers, force a
redraw.
This prevents a dodgy client from causing other clients to go into
backoff while still allowing tmux to be responsive (locally) when seeing
lots of output.

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.

Return the command client return code with MSG_EXIT now that MSG_ERROR and

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

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.
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.
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.

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).
