Marc-André Lureau 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

#
# The @device and @head parameters can be used to send the input event
# to specific input devices in case (a) multiple input devices of the

# configured input routing (see docs/multiseat.txt) for those input
# devices. The parameters work exactly like the device and head
# properties of input devices. If @device is missing, only devices
# that have no input routing config are admissible. If @device is
# specified, both input devices with and without input routing config
# are admissible, but devices with input routing config take
# precedence.

# Note: The consoles are visible in the qom tree, under
# /backend/console[$index]. They have a device link and head property,
# so it is possible to map which console belongs to which device and
# display.

# "arguments": { "events": [

#
# -> { "execute": "input-send-event" ,

#
# @egl-headless: No user interface, offload GL operations to a local
# DRI device. Graphical display need to be paired with

#
# @curses: Display video output via curses. For graphics device
# models which support a text mode, QEMU can display this
# output using a curses/ncurses interface. Nothing is
# displayed when the graphics device is in graphical mode or
# if the graphics device does not support a text
# mode. Generally only the VGA device models support text
# mode.
#
