fa6deb5866 When the data we have buffered to write to a terminal grows beyond a
reasonable amount (currently width * height * 8 bytes), discard all
output to the terminal and start trying to redraw periodically
instead. Continue with this until the amount of data we are trying to
write falls to a low level again.

This helps to prevent tmux sitting on a huge buffer of data when there
are processes with fast output running inside tmux but the outside
terminal is slow.

A new client_discarded format holds the amount of data that has been
discarded due to this mechanism.

The three variables (when to start this, when to stop, and how often to
redraw) are basically "works for me" at the moment, this is going in to
see how it goes and if it causes problems for anyone else.

8c8ce08d79 On terminals without DECSLRM, when a pane that is less than the full
with of the terminal scrolls, tmux needs to redraw the entire pane. This
results in a large amount of output data which can cause slow terminals
to struggle, particularly when many lines are scrolled together quickly.

This can be reduced by only redrawing when tmux doesn't hold any
buffered data for the terminal. If a redraw is required and data is
buffered, the redraw is deferred until all that data is consumed (it is
checked after every event loop, a timer is used to ensure this happens
at some point). While a redraw is pending, no additional data will be
written to the terminal.

The redraw still happens, now it is just pushed back if it is possible
it would just add more data on top of a terminal that is already
behind. This both gives the terminal a chance to catch up, and allows
tmux to process more scrolling (that would require additional redraws)
in the meantime.

Helps with a problem reported by Greg Hurrell.

9b28200578 Give each client a name. This defaults to the tty name as before but
falls back to an alternative if the tty name is not available. This is
clearer than overloading the client ttyname member and allows us to
remove the path stored in the tty struct, it should always be the same
as the client.

7d23d019c0 Add a window or pane id "tag" to each format tree and use it to separate
jobs, this means that if the same job is used for different windows or
panes (for example in pane-border-format), it will be run separately for
each pane.

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.

6f8cedb1bc The mouse valid flag needs to be correct before we fire the dragging

0d1be2e328 Fix so that we work out the right pane from mouse events - we were doing
so too early, before the mouse event was necessarily valid, so could end
up using the pane from the previous mouse event, or the active pane.

It is important that we use the right pane now that different panes can
have different key tables (for copy mode).

0ace779cde Initial attempt to make use of left and right margins if the terminal
supports them (that is, if it advertises itself as a VT420 - probably
just xterm). These are the vertical equivalent of the scroll region and
allow much faster scrolling of panes that do not take up the full width
of the terminal.

899e629bf0 Alerts are too slow, so rather than walking all sessions and windows,
add a link of winlinks to each window and a pointer to the session to
each winlink. Also rewrite the alerts processing to return to the old
behaviour (alert in any window sets the flag on any winlink).

ddc4512d2e Rewrite command queue handling. Each client still has a command queue,
but there is also now a global command queue. Instead of command queues
being dispatched on demand from wherever the command happens to be
added, they are now all dispatched from the top level server
loop. Command queues may now also include callbacks as well as commands,
and items may be inserted after the current command as well as at the end.

This all makes command queues significantly more predictable and easier
to use, and avoids the complex multiple nested command queues used by
source-file, if-shell and friends.

A mass rename of struct cmdq to a better name (cmdq_item probably) is
coming.

68bebe1fb7 The repeat prompt in both emacs and vi (and the old one in tmux) doesn't

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.

0509be0740 Add option to include status text in the pane borders. If
pane-border-status is set to "top" or "bottom" (rather than "off"),
every pane has a permanent top or bottom border containing the text from
pane-border-format.

Based on a diff sent long ago by Jonathan Slenders, mostly rewritten and
simplified by me.

32e510bd70 Remove support for the UTF-8 mouse extension. This was a briefly used,
poor idea that was fairly quickly replaced by SGR mouse input (which is
now widespread). It is impossible to tell the difference between UTF-8
and non-UTF-8 mouse input; since the mouse-utf8 option was removed tmux
has not handled it correctly in any case; and it is ridiculous to have
three different forms of mouse input.
