49a0f6cd99 Remove use of -netdev arg with QEMU
The QEMU 0.12.x tree has the -netdev command line argument, but not
corresponding monitor command. We can't enable the former, without
the latter since it will break hotplug/unplug.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Disable -netdev usage
  until 0.13 at earliest
* tests/qemuxml2argvtest.c: Add test for -netdev syntax
* tests/qemuxml2argvdata/qemuxml2argv-net-virtio-netdev.args,
  tests/qemuxml2argvdata/qemuxml2argv-net-virtio-netdev.xml: Test
  data files for -netdev syntax

9258ec0a2e Rewrite way QEMU PCI addresses are allocated
The current QEMU code allocates PCI addresses incrementally starting
at 4. This is not satisfactory because the user may have given some
addresses in their XML config, which need to be skipped over when
allocating addresses to remaining devices.

It is thus neccessary to maintain a list of already allocated PCI
addresses and then only allocate ones that remain unused. This is
also required for domain device hotplug to work properly later.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating
  list of existing PCI addresses, and allocating new addresses.
  Refactor address assignment to use this code
* src/qemu/qemu_driver.c: Pull PCI address assignment up into the
  qemuStartVMDaemon() method, as a prelude to moving it into the
  'define' method. Update list of allocated addresses when connecting
  to a running VM at daemon startup.
* tests/qemuxml2argvtest.c, tests/qemuargv2xmltest.c,
  tests/qemuxml2xmltest.c: Remove USB product test since all
  passthrough is done based on address
* tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.args,

1671b64702 Unset copied environment variables in qemuxml2argvtest
The test expected all environment variables copied in qemudBuildCommandLine
to have known values. So all of them have to be either set to a known value
or be unset. SDL_VIDEODRIVER and QEMU_AUDIO_DRV are not handled at all but
should be handled. Unset both, otherwise the test will fail if they are set
in the testing environment.

* src/qemu/qemu_conf.c: add a comment about copied environment variables
  and qemuxml2argvtest
* tests/qemuxml2argvtest.c: unset SDL_VIDEODRIVER and QEMU_AUDIO_DRV

febc591683 Pass -vga none if no video card specified
QEMU always configures a VGA card. If no video card is included in
the libvirt XML, it is neccessary to explicitly turn off the default
using -vga none

  handling -vga none.

16658da4e7 Convert PCI device assignment over to -device
The old syntax is

  -pcidevice host=BUS:SLOT:FUNCTION

The new syntax is

  -device pci-assign,host=BUS:SLOT:FUNCTION,addr=<PCI SLOT>,id=host0

42ce352c13 Convert USB hostdevices over to -device
The old syntax was

   -usbdevice host:PRODUCT:VENDOR

Or

   -usbdevice host:BUS.DEV

The new syntax is

   -device usb-host,product=PRODUCT,vendor=VENDOR

Or

   -device usb-host,hostbus=BUS,hostaddr=DEV

73370e9868 Convert USB disks over to -device
The previous syntax was severely limited in its options

  -usbdevice disk:/home/berrange/output.img

The new syntax is the same as for other disk types

  -drive file=/home/berrange/output.img,if=none,id=usb-1,index=1
  -device usb-storage,drive=usb-1

Again, the index= arg is wrong here, and will be removed in a
later merge

1dd6f855c3 Convert NICs over to use -device & -netdev where possible
The current syntax uses a pair of args

   -net nic,macaddr=52:54:00:56:6c:55,vlan=3,model=pcnet,name=pcnet.0
   -net user,vlan=3,name=user.0

The new syntax does not  need the vlan craziness anymore, and
so has a simplified pair of args

   -netdev user,id=user.0
   -device pcnet,netdev=user.0,id=pcnet.0,mac=52:54:00:56:6c:55,addr=<PCI SLOT>

4886cba76a Convert audio devices over to -device syntax
The current syntax for audio devices is a horrible multiplexed
arg

    -soundhw sb16,pcspk,ac97

The new syntax is

    -device sb16,id=sound0

or

    -device AC97,id=sound1,addr=<PCI SLOT>

NB, pcspk still uses the old -soundhw syntax

38a22fbfaa Convert watchdog to -device

7b2f8cdd7c Convert character devices over to use -device
The current character device syntax uses either

  -serial tty,path=/dev/ttyS2

Or

  -chardev tty,id=serial0,path=/dev/ttyS2 -serial chardev:serial0

With the new -device support, we now prefer

  -chardev file,id=serial0,path=/tmp/serial.log -device isa-serial,chardev=serial0

This patch changes the existing -chardev syntax to use this new
scheme, and fallbacks to the old plain -serial syntax for old
QEMU.

The monitor device changes to

  -chardev socket,id=monitor,path=/tmp/test-monitor,server,nowait -mon chardev=monitor

In addition, this patch adds --nodefaults, which kills off the
default serial, parallel, vga and nic devices. THis avoids the
need for us to explicitly turn each off

b81a7ece97 Fix handling of Xen(ner) detection
Latest upstream QEMU can be built with Xen support, which introduces

654c5714bf The new generic domain re-factor introduced a small regression into the drive
handling code.  In particular, if you had a section of XML like:

    <disk type='file' device='cdrom'>
      <target dev='hdc' bus='ide'/>
      <readonly/>
    </disk>

This used to work with older libvirt, but now fails.  This is because we are
actually passing the literal string (null) to the qemu command-line, which qemu
barfs on.  This patch fixes it up by making it blank, which allows qemu to
continue on it's merry way.
