Linus Torvalds 3abd3dba42 utf8: make sure to honor the array length properly
Right now the input side can give partial utf8 input, and that showed
that we didn't properly handle that case.

Linus Torvalds 3c7bd9a7d2 Make kbd macro save area use 'int' instead of short
I'm starting to expand the input value from 'short' (with flags in the
upper eight bytes) to 'int' (with negative values having flags).

Small baby steps.

Linus Torvalds ec6f4f36ec Use utf8 helper functions for keyboard input
ttgetc() used some homebrew utf8 to unicode translation, limited to just
the normal latin1 characters.  Use the utf8 helper functions to get it
right for the more complex cases.

NOTE! We don't actually handle characters > 0xff right anyway.  And we
still end up doing Latin1 in the buffers on input.  One small step at a
time.

Linus Torvalds 6b793211c2 Make cursor movement (largely) understand UTF-8 character boundaries
Ok, so it may do odd things if it's not truly utf-8, and when moving up
and down lines that have utf-8 the cursor moves oddly (because the byte
offset within the line stays constant, rather than the character
offset), but with this you can actually open the UTF8 example file and
move around it, and at least some of the movement makes sense.

Linus Torvalds 12e4647deb Remove the old utf8_mode thing.
Let's just plan on being fully utf8 some day.  We're not there yet, and
maybe we'll never be, but having the halfway mode is not useful either.

Linus Torvalds cee00b0efb Show UTF-8 input as UTF-8 output
.. by doing the stupid "convert to unicode value and back" model.

This actually populates the 'struct video' array with the unicode
values, so UTF8 input actually shows correctly.  In particular, the nice
test-file (UTF-8-demo.txt) shows up not as garbage, but as the UTF-8 it
is.

HOWEVER!

Since the *editing* doesn't know about UTF-8, and considers it just a
stream of bytes, the end result is not actually a usable utf-8 editor.
So don't get too excited yet: this is just a partial step to "actually
edit utf8 data"

NOTE NOTE NOTE! If the character buffer contains Latin1, we will
transform that Latin1 to unicode, and then output it as UTF8.  And we
will edit it correctly as the character-by-character data.  Also, we
still do the "UTF8 to Latin1" translation on *input*, so with this
commit we can actually continue to *edit* Latin1 text.

Linus Torvalds e8f984a1b0 Make the 'struct video' contain an array of unicode characters rather than bytes
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.

Linus Torvalds 12ba84c8dd spawn.c: do the "keyboard open/close" around shell invocations
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.

Linus Torvalds 33676d6d23 file.c: remove crazy keyboard open/close calls
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.

Linus Torvalds c0970c4220 Force a screen re-draw after tcap 'ti' on terminal open
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.
