e050e42678 qapi: Use explicit bulleted lists
A JSON block comment like this:
     Returns: nothing on success
              If @node is not a valid block device, DeviceNotFound
              If @name is not found, GenericError with an explanation

renders like this:

     Returns: nothing on success If node is not a valid block device,
     DeviceNotFound If name is not found, GenericError with an explanation

because whitespace is not significant.

Use an actual bulleted list, so that the formatting is correct.

449be9df52 qapi/ui.json: Avoid `...' Texinfo style quoting
Avoid Texinfo style quoting with `...', because we would like to
switch the doc comments to rST format, and rST treats it as a syntax
error. Use '...' instead, as we do in other doc comments. This looks
OK in Texinfo, and rST formats it as paired-quotation-marks.

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.

Events made conditional:

* SPICE_CONNECTED, SPICE_INITIALIZED, SPICE_DISCONNECTED,

for conditional members lands.

No HMP change, the code was already conditional.

05eb4a25ae qapi: add conditions to VNC type/commands/events on the schema
Add #if defined(CONFIG_VNC) in generated code, and adjust the
qmp/hmp code accordingly.

query-qmp-schema no longer reports the command/events etc as
available when disabled at compile.

Commands made conditional:

* query-vnc, query-vnc-servers, change-vnc-password

  Before the patch, the commands for !CONFIG_VNC are stubs that fail
  like this:

    {"error": {"class": "GenericError",
               "desc": "The feature 'vnc' is not enabled"}}

  Afterwards, they fail like this:

    {"error": {"class": "CommandNotFound",
               "desc": "The command FOO has not been found"}}

  I call that an improvement, because it lets clients distinguish
  between command unavailable (class CommandNotFound) and command failed
  (class GenericError).

Events made conditional:

* VNC_CONNECTED, VNC_INITIALIZED, VNC_DISCONNECTED

HMP change:

* info vnc

  Will return "unknown command: 'info vnc'" when VNC is compiled
  out (same as error for spice when --disable-spice)

Occurrences of VNC (case insensitive) in the schema that aren't
covered by this change:

* add_client

  Command has other uses, including "socket bases character devices".
  These are unconditional as far as I can tell.

* set_password, expire_password

  In theory, these commands could be used for managing any service's
  password.  In practice, they're used for VNC and SPICE services.
  They're documented for "remote display session" / "remote display
  server".

  The service is selected by argument @protocol.  The code special-cases
  protocol-specific argument checking, then calls a protocol-specific
  function to do the work.  If it fails, the command fails with "Could
  not set password".  It does when the service isn't compiled in (it's a
  stub then).

  We could make these commands conditional on the conjunction of all
  services [currently: defined(CONFIG_VNC) || defined(CONFIG_SPICE)],
  but I doubt it's worthwhile.

* change

  Command has other uses, namely changing media.
  This patch inlines a stub; no functional change.

80b857f0c6 ui: normalize the 'sysrq' key into the 'print' key
The 'sysrq' key was mistakenly added to QEMU to deal with incorrect handling
of the 'print' key in the ps2 device:

  commit f2289cb692
  Author: balrog <balrog@c046a42c-6fe2-441c-8c8c-71466251a162>
  Date:   Wed Jun 4 10:14:16 2008 +0000

    Add sysrq to key names known by "sendkey".

    Adding sysrq keycode to the table enabling running sysrq debugging in
    the guest via the monitor sendkey command, like:

    (qemu) sendkey alt-sysrq-t

    Tested on x86-64 target and Linux guest.

    Signed-off-by: Ryan Harper <ryanh@us.ibm.com>

The ps2 device is now fixed wrt modifiers and the 'print' key. Further the
handling of the 'sysrq' key has some problems of its own, documented in the
previous commit. To cleanup this mess, we convert any use of 'sysrq' into
'print' prior to dispatching the event to device models.
