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).

10682b9e7e Instead of loads of little screen_write_*_on and off functions which 
just change mode flags, just have screen_write_mode_set and
screen_write_mode_clear.

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).

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.
