7aa12aa215 Remove the CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE switch
GCC supports "#pragma GCC diagnostic" since version 4.6, and
Clang seems to support it, too, since its early versions 3.x.
That means that our minimum required compiler versions all support
this pragma already and we can remove the test from configure and
all the related #ifdefs in the code.

7b23d121f9 ui: increase min required GTK version to 3.22.0
Based on a mail on the qemu-devel mailing list at
https://lists.nongnu.org/archive/html/qemu-devel/2020-05/msg02909.html
and some internet research the GTK3 versions on supported
platforms are:

    RHEL-7.4: 3.22.10
    RHEL-7.5: 3.22.26
    Debian (Stretch): 3.22.11
    Debian (Buster): 3.24.5
    OpenBSD (Ports): 3.22.30
    FreeBSD (Ports): 3.22.29
    OpenSUSE Leap 15: 3.22.30
    SLE12-SP2: Unknown
    SLE15: 3.22.30
    Ubuntu (Bionic): 3.22.30
    Ubuntu (Focal): 3.24.18
    macOS (Homebrew): 3.22.30

This justifies increasing the minimum required GTK version in
QEMU to 3.22.0.

1454192746 ui/gtk: use native keyboard scancodes on Windows
Since GTK 3.22 the function gdk_event_get_scancode() is
available. On Windows this function returns keyboard scancodes
and some extended flags. These raw keyboard scancodes are much
better suited for this use case than the half-cooked win32
virtual-key codes because scancodes report the key position on
the keyboard and the positions are independent of national
language settings.

d3953bf797 ui/gtk: don't pass on win keys without keyboard grab
Without keyboard grab Windows currently handles the two win keys
and the key events are also sent to the guest. This is undesir-

plies commit c68f74b02e "win32: do not handle win keys when the
keyboard is not grabbed" from project spice-gtk to ui/gtk.c to

28b58f19d2 ui/gtk: Get display refresh rate with GDK version 3.22 or later
Commit c4c00922cc introduced the use of the GdkMonitor API, which
was introduced in GTK+ 3.22:
https://developer.gnome.org/gdk3/stable/api-index-3-22.html#api-index-3.22

  Codename:       xenial

  $ ./configure && make

GTK+ provides convenient definition in <gdk/gdkversionmacros.h>
(already include by <gdk/gdk.h>) to check which API are available.

We only use the GdkMonitor API to get the monitor refresh rate.

Extract this code as a new gd_refresh_rate_millihz() function,
and check GDK_VERSION_3_22 is defined before calling its API.
If it is not defined, return 0. This is safe and fixes our build
failure (see https://travis-ci.org/qemu/qemu/builds/636992508).

c4c00922cc display/gtk: get proper refreshrate
Because some VMs in QEMU can get GPU virtualization (using technologies
such as iGVT-g, as mentioned previously), they could produce a video
output that had a higher display refresh rate than of what the GTK
display was displaying. (fxp. Playing a video game inside of a Windows
VM at 60 Hz, while the output stood locked at 33 Hz because of defaults
set in include/ui/console.h)

Since QEMU does indeed have internal systems for determining frame
times as defined in ui/console.c.
The code checks for a variable called update_interval that it later
uses for time calculation. This variable, however, isn't defined
anywhere in ui/gtk.c and instead ui/console.c just sets it to
GUI_REFRESH_INTERVAL_DEFAULT which is 30

update_interval represents the number of milliseconds per display
refresh, and by doing some math we get that 1000/30 = 33.33... Hz

This creates the mentioned problem and what this patch does is that it
checks for the display refresh rate reported by GTK itself (we can take
this as a safe value) and just converts it back to a number of
milliseconds per display refresh.

54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

ac38378950 ui/gtk: Fix the license information
The license information in this file is very messy. A short note at
the beginning says GPL first, but the long boilerplate code then
talks about "GNU Lesser General Public License version 2.0". First,
there is no such version of the "GNU Lesser GPL", it only started with
version 2.1. In version 2.0, it was still called "GNU Library GPL"
instead. Second, you can easily get the license of this file wrong
if you only quickly glance at the long boilerplate code.

Anyway, looking at the text of the LGPL (see COPYING.LIB in the top
directory), the license clearly states in section "3." that one should
rather replace the license information with the GPL information in
such a case of a mixture instead. Thus let's clean up the confusing
statements and use the proper GPL text only.

and not all of them will honour it. Some will instead want to show the
icon listed by the .desktop file. The desktop file is located based on
the application ID, which is set using g_set_prgname. QEMU has not
historically provided a desktop file or set its app ID, so it got a
broken icon in GNOME shell, which is now fixed.

Pre-rendered icons are provided at the standard sizes expected for GUI
applications, along with the scalable SVG, to ensure maximum portability.

The PNGs are rendered from the SVG using inkscape, however, this is not
wired up into the default make rules to avoid requiring inkscape as a
mandatory tool in build systems / developer workstations.

58296cb618 ui: increase min required GTK3 version to 3.14.0
Per supported platforms doc[1], the various min GTK3 on relevant distros is:

  RHEL-7.0: 3.8.8
  RHEL-7.2: 3.14.13
  RHEL-7.4: 3.22.10
  RHEL-7.5: 3.22.26
  Debian (Stretch): 3.22.11
  Debian (Jessie): 3.14.5
  OpenBSD (Ports): 3.22.30
  FreeBSD (Ports): 3.22.29
  OpenSUSE Leap 15: 3.22.30
  SLE12-SP2: Unknown
  Ubuntu (Xenial): 3.18.9
  macOS (Homebrew): 3.22.30

This suggests that a minimum GTK3 of 3.14.0 is a reasonable target,
as users are unlikely to be stuck on RHEL-7.0/7.1 still

GTK2 was deprecated in the 2.12.0 release with:

  commit b7715af2b3
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Tue Dec 12 11:34:40 2017 +0000

    ui: deprecate use of GTK 2.x in favour of 3.x series

    The GTK 3.0 release was made in Feb, 2011:

      https://blog.gtk.org/2011/02/10/gtk-3-0-released/

    That will soon be 7 years ago, which is enough time to consider
    the 3.x series widely supported.

    Thus we deprecate the GTK 2.x support, which will allow us to
    delete it in the last release of 2018. By this time, GTK 3.x
    will be almost 8 years old.

Also return TRUE unconditionally.  This will tell gtk to ignore the

112ed241f5 qapi: Empty out qapi-schema.json
The previous commit improved compile time by including less of the
generated QAPI headers.  This is impossible for stuff defined directly
in qapi-schema.json, because that ends up in headers that that pull in
everything.

Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.

It's possible everywhere, except:

* monitor.c needs qmp-command.h to get qmp_init_marshal()

* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
  qapi-event.h to get enum QAPIEvent

Perhaps we'll get rid of those some other day.

Adding a type to qapi/migration.json now recompiles some 120 instead
of 2300 out of 5100 objects.

XkbGetKeyboard does not work in XWayland and even on non-Wayland

  https://bugs.freedesktop.org/show_bug.cgi?id=89240

This resolves a problem whereby QEMU prints

  "could not lookup keycode name"

on startup when running under XWayland. Keymap handling is
however still broken after this commit, since Xwayland is
reporting a keymap we can't handle

  "unknown keycodes `(unnamed)', please report to qemu-devel@nongnu.org"

NB, native Wayland support (which is the default under GTK3) is
not affected - only XWayland (which can be requested with GDK_BACKEND
on GTK3, and is the only option for GTK2).

27b224a61f gtk: Hardcode LC_CTYPE as C.utf-8
Commit 2cb5d2a4 removed setlocale() for everything except LC_MESSAGES in
order to avoid unwanted side effects such as using the wrong decimal
separator in generated JSON objects. However, the problem that unsetting
LC_CTYPE caused is that non-ASCII characters are considered
non-printable now and therefore the GTK menus display question marks for
accented letters, Chinese characters etc.

A first attempt to fix this [1] was rejected because even just setting
LC_CTYPE to the user's locale (and thereby modifying the semantics of
the ctype.h functions) could have unwanted effects that we're not aware
of yet.

Recently, however, glibc introduced a new locale "C.utf-8" that just
uses UTF-8 as its charset, but otherwise leaves the semantics alone.
Just setting the right character set is enough for our use case, so we
can just hardcode this one without having to be afraid of nasty side
effects.

Older systems that don't have the new locale will continue displaying
question marks, but this should fix the problem for most users.

0b663b7d77 char: remove class kind field
The class kind is necessary to lookup the chardev name in
qmp_chardev_add() after calling qemu_chr_new_from_opts() and to set
the appropriate ChardevBackend (mainly to free the right
fields).

qemu_chr_new_from_opts() can be changed to use a non-qmp function
using the chardev class typename. Introduce qemu_chardev_add() to be
called from qemu_chr_new_from_opts() and remove the class chardev kind
field. Set the backend->type in the parse callback (when non-common
fields are added).

777357d758 chardev: qom-ify
Turn Chardev into Object.

qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It
will call qemu_char_open() to open/intialize the chardev with the
ChardevCommon *backend settings.

The CharDriver::create() callback is turned into a ChardevClass::open()
which is called from the newly introduced qemu_chardev_open().

"chardev-gdb" and "chardev-hci" are internal chardev and aren't
creatable directly with -chardev. Use a new internal flag to disable
them. We may want to use TYPE_USER_CREATABLE interface instead, or
perhaps allow -chardev usage.

Although in general we keep typename and macros private, unless the type
is being used by some other file, in this patch, all types and common
helper macros for qemu-char.c are in char.h. This is to help transition
now (some types must be declared early, while some aren't shared) and
when splitting in several units. This is to be improved later.

919e11f373 gtk: use qemu_chr_alloc() to allocate CharDriverState
The gd_vc_handler() callback is using g_malloc0() to
allocate the CharDriverState struct. As a result the
logfd field is getting initialized to 0, instead of
-1 when no logfile is requested.

The result is that when running

 $ qemu-system-i386 -nodefaults -chardev vc,id=mon0 -mon chardev=mon0

qemu duplicates all monitor output to stdout as well

Not using qemu_chr_alloc() was already a bug, but harmless

fba958c692 gtk: implement set_echo
Even without line editing, this makes -qmp vc more pleasant with the
GTK+ backend.  The only issue is that set_echo is invoked very early,
long before a vc is actually associated with a VirtualConsole.  To work
around this, create a temporary VirtualConsole until then.

d20a580bc0 qapi: Change munging of CamelCase enum values
When munging enum values, the fact that we were passing the entire
prefix + value through camel_to_upper() meant that enum values
spelled with CamelCase could be turned into CAMEL_CASE.  However,
this provides a potential collision (both OneTwo and One-Two would
munge into ONE_TWO) for enum types, when the same two names are
valid side-by-side as QAPI member names.  By changing the generation
of enum constants to always be prefix + '_' + c_name(value,
False).upper(), and ensuring that there are no case collisions (in
the next patches), we no longer have to worry about names that
would be distinct as QAPI members but collide as variant tag names,
without having to think about what munging the heuristics in
camel_to_upper() will actually perform on an enum value.

Making the change will affect enums that did not follow coding
conventions, using 'CamelCase' rather than desired 'lower-case'.

Thankfully, there are only two culprits: InputButton and ErrorClass.
We already tweaked ErrorClass to make it an alias of QapiErrorClass,
where only the alias needs changing rather than the whole tree.  So
the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the
new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN).  That part
of this commit may later need reverting if we rename the enum
constants from 'WheelUp' to 'wheel-up' as part of moving
x-input-send-event to a stable interface; but at least we have
documentation bread crumbs in place to remind us (commit 513e7cd),
and it matches the fact that SDL constants are also spelled
SDL_BUTTON_WHEELUP.

c8f3f17cf1 gtk: avoid redefining _WIN32_WINNT macro
When building for Mingw64 target on Fedora 22 a warning
is issued about _WIN32_WINNT being redefined.

In file included from ui/gtk.c:40:0:

 # define _WIN32_WINNT 0x0601 /* needed to get definition of MAPVK_VK_TO_VSC */

Rather than try to get MAPVK_VK_TO_VSC defined indirectly
by defining _WIN32_WINNT, instead just define it explicitly
if missing.

2cb5d2a47c gtk: use setlocale() for LC_MESSAGES only
The QEMU code is not internationalized and assumes that it runs under
the C locale, but if we use the GTK+ UI we'll end up importing the
locale settings from the environment. This can break things, such as
the JSON generator and iotest 120 in locales that use a decimal comma.

We do however have translations for a few simple strings for the GTK+
menu items, so in order to run QEMU using the C locale, and yet have a
translated UI let's use setlocale() for LC_MESSAGES only.
