This is disgusting. And quite frankly, it's debatable whether this will
ever work. The "line" structure is still just an array of characters,
so that has to work with utf-8.
But the 'struct video' thing is what represents the actual screen
rectangle, and is fixed-size by the size of the screen. So making it
contain actual 32-bit unicode characters *may* make sense.
Right now we translate things the same way we always used to, though, so
utf-8 in 'struct line' will not be translated to the proper unicode
array, but to the bytes of the utf-8 representation. So this really
doesn't improve anything per se yet, just expands the memory use of the
video array.

I'm not 100% sure we really should even be doing this whole "keyboard"
open/close for termcap, but even if the right thing to do ends up being
to just do everything in the TTopen/TTclose (and make TTkopen/TTkclose
no-ops), it does seem to be the right thing to do.

It seems to have something to do with some old DOS mode, and not having
keyboard translation on ("Insert floppy A:" questions while opening
files? Whatever). But this is while doing normal file opens, and it is
just insane to open/close a tty across a file open.
The possible tty init/exit sequence would mess up some of the file
read/write messages.

The 'tcapkopen()' function re-initializes the terminal with the 'ti'
sequence, which for most sane termcap entries is just empty. But for
'xterm', that seems to actually be a real control sequence (clear and
reset?), and we'd better tell display.c that the screen is now garbage
and needs to be re-drawn.
Also, make tcapkclose() match the 'ti' (terminal init) with a 'te'
(terminal exit).
Maybe we should just stop playing games with ti/te, but this at least
improves the situation a bit.
