Technically speaking we should wait until we receive the QMP
greeting message before attempting to send any QMP monitor
commands. Mostly we've got away with this, but there is a race
in some QEMU which cause it to SEGV if you sent it data too
soon after startup. Waiting for the QMP greeting avoids the
race

This patch define and parse the input XML of USB redirection filter.
<devices>
...
  <redirdev bus='usb' type='spicevmc'>
    <address type='usb' bus='0' port='4'/>
  </redirdev>
  <redirfilter>
    <usbdev class='0x08' vendor='0x1234' product='0xbeef' \
            version='2.00' allow='yes'/>
    <usbdev allow='no'/>
  </redirfilter>
...
</devices>

There is no 1:1 mapping between ports and redirected devices and
qemu and spicy client couldn't decide into which usbredir ports
the client can 'plug' redirected devices. So it make sense to apply
all of filter rules global to all existing usb redirection devices.
class attribute is USB Class codes. version is bcdDevice value
of USB device. vendor and product is USB vendorId and productId.
-1 can be used to allow any value for a field. Except allow attribute
the other four are optional, default value is -1.

And redundant error resetting.

Pushed under trivial rule.

Add a qemu flag for USB redirection filter support.

The output:
usb-redir.chardev=chr
usb-redir.debug=uint8
usb-redir.filter=string
usb-redir.port=string

Recent spec file changes ensure that in distro situations, netcf
and libvirt will link against the same libnl in order to avoid
dumping core.  But for every-day development, if you use F17 and
have the libnl3-devel headers available, libvirt was blindly
linking against libnl3 even though F17 netcf still links against
libnl1, making testing a self-built binary on F17 impossible.

By making configure a little bit smarter, we can avoid this
situation - we merely skip the probe of libnl-3 if we can prove
that netcf is still using libnl-1.  I intentionally wrote the
test so that we still favor libnl-3 if netcf is not installed or
if we couldn't use ldd to determine things.

Defaults being what they are, someone will invariably complain
that our smarts were wrong.  Never fear - in that case, just run
./configure LIBNL_CFLAGS=..., where the fact that you set
LIBNL_CFLAGS (even to the empty string) will go back to probing
for libnl-3, regardless of netcf's choice.

* configure.ac (LIBNL): Don't probe libnl3 if netcf doesn't use it.

Make has a builtin operator 'undefine', and coupled with latest
automake.git, this test name ended up confusing make into thinking
the file name was meant to be used as the make operator.  Renaming

Currently qemuMonitorOpen() requires an address of the QEMU
monitor. When doing QMP based capabilities detection it is
easier if a pre-opened FD can be provided, since then the
monitor can be run on the STDIO console. Add a new API
qemuMonitorOpenFD() for such usage

virDomainDefParseString assigns 0 to port if autoport enabled.
So fix code, which check different between old and new
configurations.

Don't try to dereferece NULL pointer.

Historically, the first <console> element is treated as the
alias of a <serial> device. In the virDomainDeviceInfoIterate,
This situation is not considered. It still handles the first <console>
element as another devices, which means that for console[0] with
serial targetType, it calls callback function another time.
It will cause the problem of address conflicts when assigning
spapr-vio address for serial device on pSeries guest.

For pSeries guest, the serial configuration in the xml file
is as the following:
         <serial type='pty'>
               <target port='0'/>
               <address type='spapr-vio'/>
          </serial>

Console configuration is default, the dumped xml file is as the following:
   <serial type='pty'>
      <source path='/dev/pts/5'/>
      <target port='0'/>
      <alias name='serial0'/>
      <address type='spapr-vio' reg='0x30000000'/>
    </serial>
    <console type='pty' tty='/dev/pts/5'>
      <source path='/dev/pts/5'/>
      <target type='serial' port='0'/>
      <alias name='serial0'/>
      <address type='spapr-vio' reg='0x30000000'/>
    </console>

It shows that the <console> device is the alias of serial device.
So its address is the same as the serial device. When detecting
the conflicts in the qemuAssignSpaprVIOAddress the first console
and the serial device conflicts because virDomainDeviceInfoIterate()
still handle these as two different devices, and in the qemuAssignSpaprVIOAddress(),
it will compare these two devices' addressed. If they have same address,
it will report address conflict error.

So this patch is to handle the first console which targetType is serial
as the alias of serial device to avoid address conflicts error reported.

The implementation is done manually as the generator does not support
wrapping lists of C pointers into Python objects.

  * vshInterfaceListFree to free the interface objects list.

  * vshInterfaceListCollect to collect the interface objects, trying

This is not that ideal as API for other objects, as it's still
O(n). Because interface driver uses netcf APIs to manage the
stuffs, instead of by itself. And netcf APIs don't return a object.
It provides APIs like old libvirt APIs:

   ncf_number_of_interfaces
   ncf_list_interfaces
   ncf_lookup_by_name
   ......

Perhaps we should further improve netcf to let it provide an API
to return the object, but it could be a later patch. And anyway,
we will still benefit from the new API for the simplification,
and no race like the old APIs.
