b8ec0c713f Support insert mode by using insert character to shift the cells before writing
as normal.

93631b3ca7 Implement the DEC alignment test. With the last change this is enough for the
first cursor test in vttest (in ports) to pass; it still shops a few more
problems though.

49477de55c Fix some miscalculations when clearing to start of screen: the number of lines
to the cursor is cy not cy - 1, and the current cursor cell should be included.

28bcf774e5 New session option, status-utf8, to control the interpretation of top-bit-set
characters in status-left and status-right (if on, they are treated as UTF-8;
otherwise passed through).

1e06ec41dc Add a UTF-8 aware string length function and make UTF-8 in
status-left/status-right work properly. At the moment any top-bit-set
characters are assumed to be UTF-8: a status-utf8 option to configure this will
come shortly.

a6f2d82335 Use a (pre)randomised binary tree for UTF-8 character widths. Probably overkill
but meh.

4cbf7d489e - Ignore padding when writing so copying the screen for copy-mode doesn't include extra characters.
- Handle combined characters properly when the previous character is not UTF-8.

cf7b384c43 Better UTF-8 support, including combined characters. Unicode data is now stored
as UTF-8 in a separate array, the code does a lookup into this every time it
gets to a UTF-8 cell. Zero width characters are just appended onto the UTF-8
data for the previous cell. This also means that almost no bytes extra are
wasted non-Unicode data (yay).

Still some oddities, such as copy mode skips over wide characters in a strange
way, and the code could do with some tidying.

6c0728fe07 Step 2 of the Grand Plan To Make UTF-8 Better.
Split grid into two arrays, one containing grid attributes/flags/colours (keeps
the name grid_cell for now) and a separate with the character data (called
text). The text is stored as a u_short but is treated as a uint64_t elsewhere;
eventually the grid will have two arrays.

I'm not happy with the naming so that might change.

Still need to decide where to go from here. I'm not sure whether to combine
the peek/set functions together, and also whether to continue to treat the
text as a uint64_t (and convert to/from Unicode) or make it a char array
(of size one when UTF-8 disabled, eight when enabled) and keep everything
as UTF-8.

Also since UTF-8 will eventually become an attribute of the grid itself it
might be nice to move all the padding crap into grid.c.

514fe11727 We are going to need the updated screen data for emulating the scroll region,
which may involve changing the cursor position; however, the old (before
redraw) cursor position is necessary for writing to the tty. So, save it before
doing the redraw then update the internal screen then update the tty.

Not sure I like this solution but it does the job for now.

4428987e95 * Better support for at least the most common variant of mouse input: parse it and adjust for different panes. Also support mouse in window/session choice mode.
* Bring back the fancy window titles with session/window names: it is easy to work around problems with elinks (see FAQ).

cd8f85c2bd When I wrote this I somehow forgot that the cursor could helpfully sit at sx
(one character off the right of the screen), so there are several out-of-bounds issues. Add some additional checking.
