979313832c Extend the #[] style syntax and use that together with previous format
changes to allow the status line to be entirely configured with a single
option.

Now that it is possible to configure their content, enable the existing
code that lets the status line be multiple lines in height. The status
option can now take a value of 2, 3, 4 or 5 (as well as the previous on
or off) to configure more than one line. The new status-format array
option configures the format of each line, the default just references
the existing status-* options, although some of the more obscure status
options may be eliminated in time.

Additions to the #[] syntax are: "align" to specify alignment (left,
centre, right), "list" for the window list and "range" to configure
ranges of text for the mouse bindings.

The "align" keyword can also be used to specify alignment of entries in
tree mode and the pane status lines.

646995384d Support for windows larger than visible on the attached client. This has
been a limitation for a long time.

There are two new options, window-size and default-size, and a new
command, resize-window. The force-width and force-height options and the
session_width and session_height formats have been removed.

The new window-size option tells tmux how to work out the size of
windows: largest means it picks the size of the largest session,
smallest the smallest session (similar to the old behaviour) and manual
means that it does not automatically resize windows. The default is
currently largest but this may change. aggressive-resize modifies the
choice of session for largest and smallest as it did before.

If a window is in a session attached to a client that is too small, only
part of the window is shown. tmux attempts to keep the cursor visible,
so the part of the window displayed is changed as the cursor moves (with
a small delay, to try and avoid excess redrawing when applications
redraw status lines or similar that are not currently visible). The
offset of the visible portion of the window is shown in status-right.

Drawing windows which are larger than the client is not as efficient as
those which fit, particularly when the cursor moves, so it is
recommended to avoid using this on slow machines or networks (set
window-size to smallest or manual).

The resize-window command can be used to resize a window manually. If it
is used, the window-size option is automatically set to manual for the
window (undo this with "setw -u window-size"). resize-window works in a
similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and
-A flags. -a sets the window to the size of the smallest client (what it
would be if window-size was smallest) and -A the largest.

For the same behaviour as force-width or force-height, use resize-window
-x or -y, and "setw -u window-size" to revert to automatic sizing..

If the global window-size option is set to manual, the default-size
option is used for new windows. If -x or -y is used with new-session,
that sets the default-size option for the new session.

The maximum size of a window is 10000x10000. But expect applications to
complain and much higher memory use if making a window excessively
big. The minimum size is the size required for the current layout
including borders.

The refresh-client command can be used to pan around a window, -U -D -L
-R moves up, down, left or right and -c returns to automatic cursor
tracking. The position is reset when the current window is changed.

80c6b487dc Because we defer actually resizing applications (calling TIOCSWINSZ)
until the end of the server loop, tmux may have gone through several
internal resizes in between. This can be a problem if the final size is
the same as the initial size (what the application things it currently
is), because the application may choose not to redraw, assuming the
screen state is unchanged, when in fact tmux has thrown away parts of
the screen, assuming the application will redraw them.

To avoid this, do an extra resize if the new size is the same size as
the initial size. This should force the application to redraw when tmux
needs it to, while retaining the benefits of deferring (so we now resize
at most two times instead of at most one - and only two very rarely).

Fixes a problem with break-pane and zoomed panes reported by Michal
Mazurek.

aad4e4ddb1 Rewrite of choose mode, both to simplify and tidy the code and to add
some modern features.

Now the common code is in mode-tree.c, which provides an API used by the
three modes now separated into window-{buffer,client,tree}.c. Buffer
mode shows buffers, client mode clients and tree mode a tree of
sessions, windows and panes.

Each mode has a common set of key bindings plus a few that are specific
to the mode. Other changes are:

- each mode has a preview pane: for buffers this is the buffer content
  (very useful), for others it is a preview of the pane;

- items may be sorted in different ways ('O' key);

- multiple items may be tagged and an operation applied to all of them
  (for example, to delete multiple buffers at once);

- in tree mode a command may be run on the selected item (session,
  window, pane) or on tagged items (key ':');

- displayed items may be filtered in tree mode by using a format (this
  is used to implement find-window) (key 'f');

- the custom format (-F) for the display is no longer available;

- shortcut keys change from 0-9, a-z, A-Z which was always a bit weird
  with keys used for other uses to 0-9, M-a to M-z.

Now that the code is simpler, other improvements will come later.

Primary key bindings for each mode are documented under the commands in
the man page (choose-buffer, choose-client, choose-tree).

terminals now support it, some (lazy) applications rely on it, and it is
not hard to include now that we have pane background colours anyway.

76d6d3641f Fundamental change to how copy mode key bindings work:
The vi-copy and emacs-copy mode key tables are gone, and instead copy
mode commands are bound in one of two normal key tables ("copy-mode" or
"copy-mode-vi"). Keys are bound to "send-keys -X copy-mode-command". So:

    bind -temacs-copy C-Up scroll-up
    bind -temacs-copy -R5 WheelUpPane scroll-up

Becomes:

    bind -Tcopy-mode C-Up send -X scroll-up
    bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up

This allows the full command parser and command set to be used - for
example, we can use the normal command prompt for searching, jumping,
and so on instead of a custom one:

    bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"

command-prompt also gets a -1 option to only require on key press, which
is needed for jumping.

The plan is to get rid of mode keys entirely, so more to come eventually.

b7861f34ba Better take on reducing the name timer. Again check for name changes in
the main loop after events that may have changed the pane, but do so at
most once every 500 millis. If the pane changed too soon, use a timer to
ensure that a check happens later.

d9b3133321 Only set default title to hostname on screens that are being used for a
window pane, no point in calling gethostname() for temporary screens.

55b8d74561 Revert previous; we do need a timer, until I have a better idea. We
can't do the name check every loop, because that is too expensive, and
we can't make sure it only happens infrequently because we have no idea
when the next change will happen.

e2100c5f5f We now only checking for name changes when the active pane has changed,
but that can only happen when we have already been woken up by a read
event, so there is no need for a timer, we can just check the changed
flag on the end of that read event (we already loop over the windows to
check for bells etc anyway).

fc58e44f89 Only do the automatic-rename dance if the pane has changed (seen output,
or new active pane).

bad8d0fd20 Do not call window_unzoom from window_destroy because it will try to add
a notification which will get confused because the reference count is
already zero and end up back in window_destroy and a double
free. Instead, just destroy the layouts directly. Noticed by Thomas
Adam.

flag for move-window too. From Thomas Adam.
