36ab4c7c49 Do not draw character to screen if it has not changed, and do not save
last character if it won't be used. This (and last few commits) prompted
by a report from Hubert depesz Lubaczewski.

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).

8f1302282b Two improvements to reflow from Balazs Kezes:
- Don't extend the line to full width on insert/delete character which
  means leaves extra spaces when reflowing.

- Only mark a line wrapped when the cursor actually goes off the end,
  not on newlines which can be used for positioning.

945339b443 Allow replacing each of the many sets of separate foo-{fg,bg,attr}
options with a single foo-style option. For example:

    set -g status-fg yellow
    set -g status-bg red
    set -g status-attr blink

Becomes:

    set -g status-style fg=yellow,bg=red,blink

The -a flag to set can be used to add to rather than replace a style. So:

    set -g status-bg red

Becomes:

    set -ag status-style bg=red

Currently this is fully backwards compatible (all *-{fg,bg,attr} options
remain) but the plan is to deprecate them over time.

From Tiago Cunha.

10682b9e7e Instead of loads of little screen_write_*_on and off functions which

fdbfc7e349 Rather than having two grids for each pane, one for ASCII and one for
UTF-8, collapse the two together. Simplifies the code at the expense of
more memory (which can probably be reduced again later).

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.

79e30daeae 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.

ac3b78a841 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.
