Add a simple form of output rate limiting by counting the number of
certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
exceeds a threshold (current default 50/millisecond), start to redraw
the pane every 100 milliseconds instead of making each change as it
comes. Two configuration options - c0-change-trigger and
c0-change-interval.
This makes tmux much more responsive under very fast output (for example
yes(1) or accidentally cat'ing a large file) but may not be perfect on
all terminals and connections - feedback very welcome, particularly
where this change has a negative rather than positive effect (making it
off by default is a possibility).
After much experimentation based originally on a request Robin Lee
Powell (which ended with a completely different solution), this idea
from discussion with Ailin Nemui.
On xterm 271 and later, put the terminal into SCL 5 and use DECCRA for
scrolling the region in panes (if the large region check isn't
hit). With help from Ailin Nemui.
Support "bracketed paste" mode. This adds a -p flag to paste-buffer - if
this is used and the application has requested bracketed pastes, then
tmux surrounds the pasted text by \033[200~ and \033[201~. Applications
like vim can (apparently) use this to avoid, for example, indenting the
text. From Ailin Nemui.
Support xterm(1) cursor colour change sequences through terminfo(5) Cc
(set) and Cr (reset) extensions. Originally by Sean Estabrooks, tweaked
by me and Ailin Nemui.
Support setting the xterm clipboard when copying from copy mode using
the xterm escape sequence for the purpose (if xterm is configured to
allow it).
Written by and much discussed Ailin Nemui, guidance on
xterm/termcap/terminfo from Thomas Dickey.
Use the tsl and fsl terminfo(5) capabilities to update terminal title
and automatically fill them in on terminals with the XT capability
(which means their title setting is xterm-compatible). From hsim at
gmx.li.

Support passing through escape sequences to the underlying terminal by
using DCS with a "tmux;" prefix. Escape characters in the sequences must
be doubled. For example:
$ printf '\033Ptmux;\033\033]12;red\007\033\\'
Will pass \033]12;red\007 to the terminal (and change the cursor colour
in xterm). From Kevin Goodsell.
Move all calls to fcntl(...O_NONBLOCK) into a function and clear the
flag on the stdio file descriptors before closing them (fixes things
like "tmux ls && cat").
Support for UTF-8 mouse input (\033[1005h). This was added in xterm 262
and supports larger terminals than the older way.
If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the
same manner as the utf8 option.
With help and based on code from hsim at gmx.li.

Log:
There is somewhere that WINDOW_HIDDEN is getting set when it shouldn't
be and I can't find it, but the flag itself is a useless optimisation
that only applies to automatic-resize windows, so just dispose of it
entirely.
Fixes problems reported by Nicholas Riley.

Use UTF-8 line drawing characters on UTF-8 terminals. Fixes some stupid
terminals (I'm looking at you, putty) which disable the vt100 ACS mode
switching sequences in UTF-8 mode.
Also on terminals without ACS at all, use ASCII equivalents where
obvious.
Change the way backoff works. Instead of stopping reading from the pty
when the client tty backs up too much, just stop updating the tty and
only update the internal screen. Then when the tty recovers, force a
redraw.
This prevents a dodgy client from causing other clients to go into
backoff while still allowing tmux to be responsive (locally) when seeing
lots of output.
Fix problems with window sizing seen by Raghavendra D Prabhu when
starting tmux from .xinitrc.
One of the very few things the server relies on the client for now is to
pass through a message on SIGWINCH, but there is a condition where
potentially a SIGWINCH may be lost during the transition from unattached
(main.c) to attached (client.c). So trigger a size change immediately
after the client installs its SIGWINCH handler.
Also, when the terminal is resized, reset the scroll region and cursor
position. Previously, we were clearing our saved idea of these, but in
fact some terminals do not reset them on resize, so this caused problems
during redraw.
While here make a resize to the same size not cause a redraw and rename
the tmux.out output log file to include the tmux PID.
When the mode-mouse option is on, support dragging to make a selection
in copy mode.
Also support the scroll wheel, although xterm strangely does not ignore
it in application mouse mode, causing redraw artifacts when scrolling up
(other terminals appear to be better behaved).
Check for colour and attribute modifications early so the translated
values can be stored in the cached terminal attributes rather than the
requested (untranslated) values. Prevents tmux clearing and setting the
attributes for every character when using aixterm colours.
