962cf8fd4f ui/curses: manipulate cchar_t with standard curses functions
The chars/attr fields are curses internals, setcchar and getcchar have
to be used instead.

b7b664a4fe ui/curses: do not assume wchar_t contains unicode
E.g. BSD and Solaris even use locale-specific encoding there.

We thus have to go through the native multibyte representation and use
mbrtowc/wcrtomb to make a proper conversion.

2f8b7cd587 curses: add option to specify VGA font encoding
This uses iconv to convert glyphs from the specified VGA font encoding to
unicode, and makes use of cchar_t instead of chtype when using ncursesw,
which allows to store all wide char as well as the WACS values. The default
charset is made CP437 since that is the charset of the hardware default VGA
font. This also makes the curses backend set the LC_CTYPE locale to "" to
allow curses to emit wide characters.

459a707ecc curses: support wide input
This makes use of wide curses functions instead of 8bit functions. This
allows to type e.g. accented letters.

Unfortunately, key codes are then returned with values that could be
confused with wide characters by ncurses, so we need to add a maybe_keycode
variable to know whether the returned value is a key code or a character
(curses with wide support), or possibly both (curses without wide support).

The translation tables thus also need to be separated into key code
translation and character translation.  The curses2foo helper makes it easier
to use them.

633786fea7 Reduce curses escdelay from 1s to 25ms
By default, curses will only report single ESC key event after 1s delay,
since ESC is also used for keypad escape sequences. This however makes
users believe that ESC is not working. Reducing to 25ms provides good user
experience, while still allowing 25ms for keypad sequences to get in, which
should be enough.

19c1b9fd3d keymap: fix keyup mappings
It is possible that the modifier state on keyup is different from the
modifier state on keydown.  In that case the keycode lookup can end up
with different keys in case multiple keysym -> keycode mappings exist,
because it picks the mapping depending on modifier state.

To fix that change the lookup logic for keyup events.  Instead of
looking at the modifier state check the key state and prefer a keycodes
where the key is in "down" state right now.

f27ff81070 curses: Fix compiler warnings (Mingw-w64 redefinition of macro KEY_EVENT)
For builds with Mingw-w64 as it is included in Cygwin, there are two
header files which define KEY_EVENT with different values.

This results in lots of compiler warnings like this one:

  CC      vl.o
In file included from /qemu/include/ui/console.h:340:0,
                 from /qemu/vl.c:76:
/usr/i686-w64-mingw32/sys-root/mingw/include/curses.h:1522:0: warning: "KEY_EVENT" redefined
 #define KEY_EVENT 0633  /* We were interrupted by an event */

In file included from /usr/share/mingw-w64/include/windows.h:74:0,
                 from /usr/share/mingw-w64/include/winsock2.h:23,
                 from /qemu/include/sysemu/os-win32.h:29,
                 from /qemu/include/qemu/osdep.h:100,

/usr/share/mingw-w64/include/wincon.h:101:0: note: this is the location of the previous definition
 #define KEY_EVENT 0x1

QEMU only uses the KEY_EVENT macro from wincon.h.
Therefore we can undefine the macro coming from curses.h.

The explicit include statement for curses.h in ui/curses.c is not needed
and was removed.

Those two modifications fix the redefinition warnings.

code was added to QEMU in 2008.)

4083733db5 ui/curses: Fix color attribute of monitor for curses
Current text_console_update() writes totally broken color attributes
to console_write_ch(). The format now is writing,

[WRONG]
	bold << 21 | fg << 12 | bg << 8 | char
	fg == 3bits curses color number
	bg == 3bits curses color number

I can't see this format is where come from. Anyway, this doesn't work
at all.

What curses expects is actually (and vga.c is using),

[RIGHT]
	bold << 21 | bg << 11 | fg << 8 | char
	fg == 3bits vga color number
	bg == 3bits vga color number

And curses set COLOR_PAIR() up to match this format, and curses's
chtype. I.e,

	bold | color_pair | char
	color_pair == (bg << 3 | fg)

To fix, this simply uses VGA color number everywhere except curses.c
internal. Then, convert it to above [RIGHT] format to write by
console_write_ch(). And as bonus, this reduces to expose curses define
to other parts (removes COLOR_* from console.c).

[Tested the first line is displayed as white on blue back for monitor
in curses console]

fedf0d35aa ui: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).  Same Coccinelle semantic patch as in commit b45c03f.
