4ede35c48c Accept the OSC 52 escape sequence inside tmux to add a new buffer, from 
harry dot gindi at live dot com.

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.

1fd6ca2260 Instead of representing colours in several different forms with various 
cell flags, convert to use an int with flags marking 256 or RGB colours
in the top byte (except in cells, which we don't want to make any
bigger). From Brad Town.

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.

Mostly from Suraj N Kurapati, based on a diff originally by someone else.

99e9a4c786 send-keys -R should reset the input parser to ground state (so it can be 
used to escape from, for example, printf '\033]2;').

2adf3f42ee Partly revert previous, it is harmless to keep support for UTF-8 mouse 
mode inside tmux, just no longer support it for tmux itself.

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 
terminal. We still support non-UTF-8 terminals outside tmux, but inside
it is always UTF-8 (as when the utf8 and status-utf8 options were on).

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.

f4fdddc930 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.

1af09d6330 Try to reduce the UTF-8 mess. 
Get rid of passing around u_char[4]s and define a struct utf8_data which has
character data, size (sequence length) and width. Move UTF-8 character
collection into two functions utf8_open/utf8_append in utf8.c which fill in
this struct and use these functions from input.c and the various functions in
screen-write.c.

Space for rather more data than is necessary for one UTF-8 sequence is in the
utf8_data struct because screen_write_copy is still nasty and needs to reinject
the character (after combining) into screen_write_cell.

8dd2f0da3f More input compatibility love. Support C0 within escape sequences, and the C0 
control character VT (vertical tab, \013), which is treated as LF like
VT102. Makes another vttest happy.

52ec9b9ec4 Implement the DEC alignment test. With the last change this is enough for the

problems though.

2faec76afa Pass window titles through vis(1). <0x20 is dropped anyway by the input state 
machine but top-bit-set nonprintables could cause trouble, and they are neater
like this anyway.
