9cc02d1498 Trying to avoid the occasional newline by saving the last cell on screen
is not actually helping us much and just adds complexity, so don't
bother.

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.

e83ebf50de Fix a couple of problems with insert mode: flush dirty cells before we
modify the screen, not after; and use grid_view_insert_cells to make
space not grid_move_cells.

30086e504c screen_write_copy tried to be clever and clear the line if it reached
the end of the source, but it was wrong and causes problems that are
only showing up now we are more aggressive about skipping redundant
screen updates. Remove the optimization entirely as more trouble than it
is worth to fix (and it'll have to go when BCE is done anyway).

cf7f3a436a Check padding when writing any character with width > 1, in case they
overlap after the first character (for example with cells xy and ab, y
is replacing a).

2627ab322e Remember the number of lines scrolled into the history (versus cleared
into the history) and when resizing only use scrolled lines and not
cleared lines (which are probably not intended to reappear). From

0f73af876f Don't update cells in each block of data read from a pane immediately,
instead track them as change (dirty) and update them once at the end,
saves much time if repeatedly writing the same cell. Also fix comparison
of cells being equal in a few places (memcmp is not enough).

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.

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).
