31e3f2d530 Support code for control mode flow control: allow clients to have 
separate offsets (used and acknowleged) into the pane buffers; turn off
reading from panes when no clients can accept the data; and add a -A

0ab82d9531 Add a terminal feature for enable/disable extended keys (supported by 
xterm and mintty) and add an option to make tmux send it. Only forward
extended keys if the application has requested them, even though we use
the CSI u sequence and xterm uses CSI 27 ~ - this is what mintty does as
well.

9605b080f6 Do not hoke into struct window_pane from the tty code and instead set 
everything up in tty_ctx. Provide a way to initialize the tty_ctx from a
callback and use it to let popups draw directly through input_parse in
the same way as panes do, rather than forcing a full redraw on every
change.

f03b61131b Drop having a separate type for style options and make them all strings, 
which allows formats to be expanded. Any styles without a '#{' are still
validated when they are set but any with a '#{' are not. Formats are not
expanded usefully in many cases yet, that will be changed later.

To make this work, a few other changes:

- set-option -a with a style option automatically appends a ",".

- OSC 10 and 11 don't set the window-style option anymore, instead the
  fg and bg are stored in the pane struct and act as the defaults that
  can be overridden by window-style.

- status-fg and -bg now override status-style instead of trying to keep
  them in sync.

5f92f92908 Add a per-pane option set. Pane options inherit from window options (so 
there should be no change to existing behaviour) and are set and shown
with set-option -p and show-options -p.

Change remain-on-exit and window-style/window-active-style to be pane
options (some others will be changed later).

This makes select-pane -P and -g unnecessary so no longer document them
(they still work) and no longer document set-window-option and
show-window-options in favour of set-option -w and show-options -w.

13a0b6bb3f Collect sequences of printable ASCII characters and process them 
together instead of handling them one by one. This is significantly
faster. Sequences are terminated when we reach the end of the line, fill
the internal buffer, or a different character is seen by the input
parser (an escape sequence, or UTF-8).

Rather than writing collected sequences out immediately, hold them until
it is necessary (another screen modification, or we consume all
available data). This means we can discard changes that would have no
effect (for example, lines that would just be scrolled off the screen or
cleared). This reduces the total amount of data we write out to the
terminal - not important for fast terminals, but a big help with slow
(like xterm).

dd0c814779 Implement "all event" (1003) mouse mode but in a way that works. The 
main issue is that if we have two panes, A with 1002 and B with 1003, we
need to set 1003 outside tmux in order to get all the mouse events, but
then we need to suppress the ones that pane A doesn't want. This is easy
in SGR mouse mode, because buttons == 3 is only used for movement events
(for other events the trailing m/M marks a release instead), but in
normal mouse mode we can't tell so easily. So for that, look at the
previous event instead - if it is drag+release as well, then the current
event is a movement event.

4179b42424 Add support for BCE (background colour erase). This makes various escape 
sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank
cells using the current background colour rather than the default
colour.

On modern systems BCE doesn't really have many benefits, but most other
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.

427b820426 Support for RGB colour, using the extended cell mechanism to avoid 
wasting unnecessary space. The 'Tc' flag must be set in the external

tmux will map to the closest of the 256 or 16 colour palettes.
