3b35daacf7 If the current screen was complex enough, it was possible to make redraw
itself hit the "terminal can't keep up" check. To avoid this, record how
much data we send during redraw (we know we will be starting with 0) and
skip the check until it has been flushed. GitHub issue 912.

d52f579fd5 Up to now, tmux sees \033\033[OA as M-Up and since we turned on
xterm-keys by default, generates \033[1;3A instead of
\033\033[OA. Unfortunately this confuses vi, which doesn't understand
xterm keys and now sees Escape+Up pressed within escape-time as Escape
followed by A.

The issue doesn't happen in xterm itself because it gets the keys from X
and can distinguish between a genuine M-Up and Escape+Up.

Because xterm can, tmux can too: xterm will give us \033[1;3A (that is,
kUP3) for a real M-Up and \033\033OA for Escape+Up - in fact, we can be
sure any \033 preceding an xterm key is a real Escape key press because
Meta would be part of the xterm key instead of a separate \033.

So change tmux to recognise both sequences as M-Up for its own purposes,
but generate the xterm version of M-Up only if it originally received
the xterm version from the terminal.

This means we will return to sending \033\033OA instead of the xterm key
for terminals that do not support xterm keys themselves, but there is no
practical way around this because they do not allow us to distinguish
between Escape+Up and M-Up. xterm style escape sequences are now the de
facto standard for these keys in any case.

Problem reported by jsing@ and subsequently by Cecile Tonglet in GitHub
issue 907.

0ccfb61bb0 In order that people can use formats like #D in #() in the status line
and not have to wait for an update when they change pane, we allow
commands to run more than once a second if the expanded form
changes. Unfortunately this can mean them being run far too often
(pretty much continually) when multiple clients exist, because some
formats (including #D) will always differ between clients.

To avoid this, give each client its own tree of jobs which means that
the same command will be different instances for each client - similar
to how we have the tag to separate commands for different panes.

GitHub issue 889; test case reported by Paul Johnson.

2c0f826c36 Mouse bindings and hooks set up an initial current state when running a
command. This is used for the session, window and pane for all commands
in the command sequence if there is no -t or -s.

However, using it for all commands in the command sequence means that if
the active pane or current session is changed, subsequent commands still
use the previous state. So make commands which explicitly change the
current state (such as neww and selectp) update it themselves for later
commands. Commands which may invalidate the state (like killp) are
already OK because an invalid state will be ignored.

Also fill in the current state for all key bindings rather than just the
mouse, so that any omissions are easier to spot.

92a77e7654 It is annoying that the copy mode key table (or any other key table)
will suppress root key table bindings. So change to always check the
root table if no binding is found in the current table (whether it be
the prefix table from pressing the prefix or the copy mode table from a
pane).

A root key binding can be blocked by binding the key to a command that
does nothing (like send-keys with no arguments).

Problem reported by Thomas Sattler.

51a0dbb172 Only set up a current target for mouse key bindings. Fixes:
bind q select-pane -U \; resize-pane -Z

(There is still some possible weirdness with the way we do current
targets, it should probably be done in a different way at some point.)

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.
