ac19b51678 Add qemu qcode support for keys F13 to F24
To be able to use the function keys F13 to F24 these should be defined in de keycodemapdb and added to the qapi.
The keycodemapdb is updated in its own repository, this patch enables the use of those keys within qemu.

dbccb1a5a1 gtk: Add show_menubar=on|off command line option.
The patch adds "show_menubar" command line option for GTK UI similar to
"show_tabs". This option allows to hide menu bar initially, it still can
be toggled by shortcut and other shortcuts still work.

9eafdeeac3 ui: Switch "-display sdl" to use the QAPI parser
The "-display sdl" option still uses a hand-crafted parser for its
parameters since we didn't want to drag an interface we considered
somewhat flawed into the QAPI schema. Since the flaws are gone now,
it's time to QAPIfy.

This introduces the new "DisplaySDL" QAPI struct that is used to hold
the parameters that are unique to the SDL display. The only specific
parameter is currently "grab-mod" that is used to specify the required
modifier keys to escape from the mouse grabbing mode.

f844cdb997 ui/cocoa: capture all keys and combos when mouse is grabbed
Applications such as Gnome may use Alt-Tab and Super-Tab for different
purposes, some use Ctrl-arrows so we want to allow qemu to handle
everything when it captures the mouse/keyboard.

However, Mac OS handles some combos like Command-Tab and Ctrl-arrows
at an earlier part of the event handling chain, not letting qemu see it.

We add a global Event Tap that allows qemu to see all events when the
mouse is grabbed. Note that this requires additional permissions.

675fd3c96b qapi/monitor: allow VNC display id in set/expire_password
It is possible to specify more than one VNC server on the command line,
either with an explicit ID or the auto-generated ones à la "default",
"vnc2", "vnc3", ...

It is not possible to change the password on one of these extra VNC
displays though. Fix this by adding a "display" parameter to the
"set_password" and "expire_password" QMP and HMP commands.

For HMP, the display is specified using the "-d" value flag.

For QMP, the schema is updated to explicitly express the supported
variants of the commands with protocol-discriminated unions.

142ca628a7 ui: add a D-Bus display backend
The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.

By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.

The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.

The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:

$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0

org.qemu.Display1.Console           interface -         -               -

66c2207fd2 ui: Make the DisplayType enum entries conditional
Libvirt's "domcapabilities" command has a way to state whether certain
graphic frontends are available in QEMU or not. Originally, libvirt
looked at the "--help" output of the QEMU binary to determine whether
SDL was available or not (by looking for the "-sdl" parameter in the
help text), but since libvirt stopped doing this analysis of the help
text, the detection of SDL is currently broken, see:

 https://bugzilla.redhat.com/show_bug.cgi?id=1790902

QEMU should provide a way via the QMP interface instead. A simple way,
without introducing additional commands, is to make the DisplayType
enum entries conditional, so that the enum only contains the entries if
the corresponding CONFIG_xxx switches have been set. This of course
only gives an indication which possibilities have been enabled during
compile-time of QEMU (and does not take into account whether modules
are later available or not for example - for this we'd need a separate
command), but anyway, this should already be good enough for the above
bug ticket, and it's a good idea anyway to make the QMP interface
conditional here, so let's simply do it.

0d9b90ce5c console: make QMP/HMP screendump run in coroutine
Thanks to the monitors' coroutine support (merge commit b7092cda1b),
the screendump handler can trigger a graphic_hw_update(), yield and let
the main loop run until update is done. Then the handler is resumed, and
ppm_save() will write the screen image to disk in the coroutine context.

The IO is still blocking though, as the file is set blocking so far,
this could be addressed by some future change (with other caveats).

f7160f3218 schemas: Add vim modeline
The various schemas included in QEMU use a JSON-based format which
is, however, strictly speaking not valid JSON.

As a consequence, when vim tries to apply syntax highlight rules
for JSON (as guessed from the file name), the result is an unreadable
mess which mostly consist of red markers pointing out supposed errors
in, well, pretty much everything.

Using Python syntax highlighting produces much better results, and
in fact these files already start with specially-formatted comments
that instruct Emacs to process them as if they were Python files.

This commit adds the equivalent special comments for vim.

bb5ccf225e qapi: Delete all the "foo: dropped in n.n" notes
A handful of QAPI doc comments include lines like
"ppcemb: dropped in 3.1". The doc comment parser will just
put these into whatever the preceding section was; sometimes
that's "Notes", and sometimes it's some random other section,
as with "NetClientDriver" where the "'dump': dropped in 2.12"
line ends up in the "Since:" section.

This tends to render wrongly, more so in the upcoming rST
generator, but sometimes even in the Texinfo, as in the case
of QKeyCode:
   ac_bookmarks
       since 2.10 altgr, altgr_r: dropped in 2.10

Since commit 3264ffced3 (v4.2.0), we have a better place to tell
users about deprecated and deleted functionality --
qemu-deprecated.texi.  These "dropped in" remarks all predate it, and
other feature drops of that vintage are not documented anywhere, so
moving these to qemu-deprecated.texi makes little sense.  Drop them
instead.

because whitespace is not significant.

43d7c2d06e qapi/ui.json: Put input-send-event body text in the right place
In the doc comment for input-send-event, there is a multi-line
chunk of text ("The @device...take precedence") which is intended
to be the main body text describing the event. However it has
been placed after the arguments and Returns: section, which
means that the parser actually thinks that this text is
part of the "Returns" section text.

Move the body text up to the top so that the parser correctly
classifies it as body.

26ec4e53f2 qapi: Fix indent level on doc comments in json files
The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.

Make the doc comments more strongly consistent about indentation
for multiline constructs like:

@arg: description line 1
      description line 2

Returns: line one
         line 2

so that there is always exactly one space after the colon, and
subsequent lines align with the first.

This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace).  This does mean that we end up with some
over-length lines.

Note that when the documentation for an argument fits on a single
line like this:

@arg: one line only

then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

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.

d8aec9d9f1 display: add -display spice-app launching a Spice client
Add a new display backend that will configure Spice to allow a remote
client to control QEMU in a similar fashion as other QEMU display
backend/UI like GTK.

For this to work, it will set up Spice server with a unix socket, and
register a VC chardev that will be exposed as Spice ports. A QMP
monitor is also exposed as a Spice port, this allows the remote client
fuller qemu control and state handling.

- doesn't handle VC set_echo() - this doesn't seem a strong
  requirement, very few front-end use it
- spice options can be tweaked with other -spice arguments
- Windows support shouldn't be hard to do, but will probably use a TCP
  port instead
- we may want to watch the child process to quit automatically if it
  crashed

2657846fb2 input-linux: customizable grab toggle keys
This patch adds a new option to the input-linux object:

grab-toggle=[key-combo]

The key combination can be one of the following:

* ctrl-ctrl
* alt-alt
* meta-meta
* scrolllock
* ctrl-scrolllock

The user can pick any of these key combinations. The VM's grab
of the evdev device will be toggled when the key combination is
pressed.

Any invalid setting will result in an error. No setting will
result in the current default of ctrl-ctrl.

The right and left ctrl key both work for Ctrl-Scrolllock.

If scrolllock is selected as one of the grab-toggle keys, it
will be entirely disabled and not passed to the guest at all.
This is to prevent enabling it while attempting to leave or enter
the VM. On the host, scrolllock can be disabled using xmodmap.

First, find the modifier that Scroll_Lock is bound to:

$ xmodmap -pm

Then, remove Scroll_Lock from it, replacing modX with the modifier:

$ xmodmap -e 'remove modX = Scroll_Lock'

If Scroll_Lock is not bound to any modifier, it is already disabled.

To save the changes, add them to your xinitrc.
