Switch tmux to use imsg. This is the last major change to make the
client-server protocol more resilient and make the protocol versioning work
properly. In future, the only things requiring a protocol version bump will be
changes in the message structs, and (when both client and server have this
change) mixing different versions should nicely report an error message.
As a side effect this also makes the code tidier, fixes a problem with the way
errors reported during server startup were handled, and supports fd passing
(which will be used in future).
Looked over by eric@, thanks.
Please note that mixing a client with this change with an older server or vice
versa may cause tmux to crash or hang - tmux should be completely exited before
upgrading.

Reset the attributes after drawing all or part of the screen, and reset the
region before poll(2). This reduces (but does not eliminate) the chance of the
attributes not being normal if tmux is disconnected without warning (ssh ~.,
reboot from inside, etc).

If there is an error in the configuration file, don't just exit(1) as this can
cause the client to hang. Instead, send the error message, then mark the client
as bad and start a normal shutdown so the server exits once the error is
written.
This also allows some code duplicating daemon(3) to be trimmed and logging to
begin earlier.
Prompted by Theo noticing the behaviour on error wasn't documented.

Next step towards customisable mode keys: build each default table of keys
into a named tree on start and use that for lookups. Also add command to string
translation tables and modify list-keys to show the mode key bindings (new
-t argument).

translation tables and modify list-keys to show the the mode key bindings (new

Permit commands to be bound to key presses without the prefix key first. The
new -n flag to bind-key and unbind-key sets or removes these bindings, and
list-key shows them in []s.
Each window now has a tree of layout cells associated with it. In this tree,
each node is either a horizontal or vertical cell containing a list of other
cells running from left-to-right or top-to-bottom, or a leaf cell which is
associated with a pane.
The major functional changes are:
- panes may now be split arbitrarily both horizontally (splitw -h, C-b %) and
vertically (splitw -v, C-b ");
- panes may be resized both horizontally and vertically (resizep -L/-R/-U/-D,
bound to C-b left/right/up/down and C-b M-left/right/up/down);
- layouts are now applied and then may be modified by resizing or splitting
panes, rather than being fixed and reapplied when the window is resized or
panes are added;
- manual-vertical layout is no longer necessary, and active-only layout is gone
(but may return in future);
- the main-pane layouts now reduce the size of the main pane to fit all panes
if possible.
Thanks to all who tested.
If these are enabled (and the monitor-activity, bell-action and monitor-content
options are configurated appropriately), when activity, a bell, or content is
detected, a message is shown.
Also tidy up the bell/activity/content code in server.c slightly and fix a
couple of errors.

frees the command list bound to the key while it is still being executed,
leading to a use after free. To prevent this, create a dead keys list and defer
freeing replaced or removed key bindings until the main loop when the key
binding will have finished executing.
Found by Johan Friis when creating a key binding to reload his configuration
file.

Also display the line number and the entire line in the results, and lose the

highlight the status line if it matches.
- To make this possible, the function cmd_find_window_search from
cmd-find-window.c had to be moved to window.c and renamed window_pane_search.
- While there use three new functions in server.c to check for bell, activity,
and content, to avoid too much nesting.
script which must be run before building.
Still two makefiles but they are a hell of a lot simpler.
HAVE_* also will make it easier to move to $buildsystem if necessary later.
redraw the entire window. Also add a flag to skip updating the window any
further if it is scheduled to be redrawn. This has the effect of batching
multiple redraws together.
issues - particularly, don't mix with manual pane resizing and be careful when
viewing from multiple clients; generally cycling the layout a few times will
fix most problems. Getting this in for testing while I think about how to deal
with manual mode.
Split window as normal and cycle the layouts with C-b space. Some of the
layouts will work better when swap-pane comes along.
tmux-1000. The default socket is thus /tmp/tmux-UID/default. To start a
separate server, the new -L command line option should be used: this creates a
socket in the same directory with a different name ("-L main" will create
socket called "main"). -S should only be used to place the socket outside
/tmp. This makes sockets a little more secure and a bit more convenient to use
multiple servers.
by reading argv[0] from the process group leader of the group that owns the tty
(tcgetpgrp()). This can't be done portably so some OS-dependent code is
introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment.
A new window flag, automatic-rename, is available: if this is set to off, the
window name is not changed. Specifying a name with the new-window, new-session
or rename-window commands will automatically set this flag to off for the
window in question. To disable it entirely set the option to off globally (setw
-g automatic-rename off).
an arbitrary width and height (0 for the default unlimited). This is neat for
emacs which doesn't have a sensible way to force hard wrapping at 80
columns. Also, don't try to be clever and use clr_eol when redrawing the
whole screen, it causes trouble since the redraw functions are used to draw
the blank areas too.
