a51668ca06 Support OSC 52 ? to read the top buffer inside tmux (when set-clipboard 
is changed to on), also add refresh-client -l to ask tmux to use the
same mechanism to get the clipboard from the terminal outside
tmux. GitHub issue 1477.

051a29ca03 A couple of fixes to the : form of SGR. Apparently there is an extra 
argument that nobody knew about, so skip that if it exists. Also there
are a bunch of useless optional arguments at the end, so ignore those.

85c48aafff For some reason tmux treats SGR 10 as SGR 0. It has done since the first 
version and I'm not sure why since no other terminal appears to. Change
to just ignore SGR 10 instead.

82db1fa9e5 There are buggy terminals out there that do not move the cursor to 0,0

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.

Mostly written by Sean Haugh.

b8a102d26f Handle wcwidth() and mbtowc() failures in better style and drop 
characters where we can't find the width (wcwidth() fails) on input, the
same as we drop invalid UTF-8. Suggested by schwarze@.

427b820426 Support for RGB colour, using the extended cell mechanism to avoid 
wasting unnecessary space. The 'Tc' flag must be set in the external
TERM entry (using terminal-overrides or a custom terminfo entry), if not
tmux will map to the closest of the 256 or 16 colour palettes.

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.

c5689a5a40 Long overdue change to the way we store cells in the grid: now, instead 
of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.

This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.

The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.

1b86f520ea Nuke the utf8 and status-utf8 options and make tmux only a UTF-8

f59971276a 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.

like vim can (apparently) use this to avoid, for example, indenting the
text. From Ailin Nemui.
