f78610038d qemu: assume -drive argument is always available
As of QEMU 0.9.1 the -drive argument can be used to configure
all disks, so the QEMU driver can assume it is always available
and drop support for -hda/-cdrom/etc.

Many of the tests need updating because a great many were
running without CAPS_DRIVE set, so using the -hda legacy
syntax.

Fixing the tests uncovered a bug in the argv -> xml
convertor which failed to handle disk with if=floppy.

ad1748a1aa qemu: add capabilities bit for device xio3130-downstream
The downstream ports of an x3130-upstream switch can each have one of
these plugged into them (and that is the only place they can be
connected). Each xio3130-downstream provides a single PCIe port that
can have PCI or PCIe devices hotplugged into it. Apparently an entire
set of x3130-upstream + several xio3130-downstreams can be hotplugged
as a unit, but it's not clear to me yet how that would be done, since
qemu only allows attaching a single device at a time.

This device will be used to implement the
"pcie-switch-downstream-port" model of pci controller.

25bf888a66 Report original error when QMP probing fails with new QEMU
If probing capabilities via QMP fails, we now have a check
that prevents us falling back to -help parsing. Unfortunately
the error message

  "Failed to probe capabilities for /usr/bin/qemu-kvm:
   unsupported configuration: QEMU 2.1.2 is too new for help parsing"

is proving rather unhelpful to the user. We need to be telling
them why QMP failed (the root cause), rather than they can't
use -help (the side effect).

To do this we should capture stderr during QMP probing, and
if -help parsing then sees a new QEMU version, we know that
QMP should have worked, and so we can show the messages from
stderr. The message thus becomes

  "Failed to probe capabilities for /usr/bin/qemu-kvm:
   internal error: QEMU / QMP failed: Could not access
   KVM kernel module: No such file or directory
   failed to initialize KVM: No such file or directory"

ae3e29e6e7 qemu: Don't try to parse -help for new QEMU
Since QEMU 1.2.0, we switched to QMP probing instead of parsing -help
(and other commands, such as -cpu ?) output. However, if QMP probing
failed, we still tried starting QEMU with various options and parsing
the output, which was guaranteed to fail because the output changed.
Let's just refuse parsing -help for QEMU >= 1.2.0.

17133e3702 qemu: add host-pci-multidomain capability
Quite a long time ago, (apparently between qemu 0.12 and 0.13) qemu
quietly began supporting the optional specification of a domain in the
host-side address of all pci passthrough commands (by simply
prepending it to the bus:slot.function format, as
"dddd:bb:ss.f"). Since machines with multiple PCI domains are very
rare, this never came up in practice, so libvirt was never updated to
support it.

This patch takes the first step to supporting specification of a non-0
domain in the host-side address of PCI devices being assigned to a
domain, by adding a capability bit to indicate support
"QEMU_CAPS_HOST_PCI_MULTIDOMAIN", and detect it. Since this support
was added in a version prior to the minimum version required for
QMP-style capabilities detection, the capability is always enabled for
any qemu that uses QMP for capabilities detection. For older qemus,
the only clue that a domain can be specified in the host pci address
is the presence of the string "[seg:]" in the help string for
-pcidevice. (Ironically, libvirt will not be modified to support
specification of domain for -pcidevice, since any qemu new enough for
us to care about also supports "-device pci-assign" or "-device
vfio-pci", which are greatly preferred).

feba2febce qemu: Support setting the 'removable' flag for USB disks
Add an attribute named 'removable' to the 'target' element of disks,
which controls the removable flag. For instance, on a Linux guest it
controls the value of /sys/block/$dev/removable. This option is only
valid for USB disks (i.e. bus='usb'), and its default value is 'off',
which is the same behaviour as before.

To achieve this, 'removable=on' (or 'off') is appended to the '-device
usb-storage' parameter sent to qemu when adding a USB disk via
'-disk'. A capability flag QEMU_CAPS_USB_STORAGE_REMOVABLE was added
to keep track if this option is supported by the qemu version used.

f03dcc5df1 qemu: Allow migration over IPv6
Allow migration over IPv6 by listening on [::] instead of 0.0.0.0
when QEMU supports it (QEMU_CAPS_IPV6_MIGRATION) and there is
at least one v6 address configured on the system.

Use virURIParse in qemuMigrationPrepareDirect to allow parsing
IPv6 addresses, which would cause an 'incorrect :port' error
message before.

Move setting of migrateFrom from qemuMigrationPrepare{Direct,Tunnel}
after domain XML parsing, since we need the QEMU binary path from it
