The code historically skipped the 'format' field for 'raw' images as we
didn't output it when no format support was present. Stop misleading and
output the format also for 'raw' images.

All Xen PV and HVM with PV driver support a memory balloon device,
which cannot be disabled through the toolstack. Model the device
in the libxl driver, similar to the recently removed xend-based
driver.

It is possible to crash libvirtd when converting xl native config to
domXML when the xl config contains an empty disk source, e.g. an empty
CDROM. Fix by checking that the disk source is non-NULL before parsing it.

Some of the test configuration files in tests/xlconfigdata
use the old qemu-dm as the emulator. Many of the configuration
features tested (spice, rbd, multi-usb) are not even usable with
the old qemu. Change these files to use the new qemu-xen (also
known as qemu upstream) emulator.
Note: This change fixes xlconfigtest failures when the old
qemu is actually installed on the system. During device post
parse, the libxl driver attempts to invoke the emulator to
determine if it is the old or new qemu so it can properly set
video RAM defaults. With the old qemu installed, the default
video RAM was set differently than the expected value.
Changing all the test data files to use qemu-xen ensures
predictable results wrt default video RAM size.

The most formal form of xl disk configuration uses key=value
syntax to define each configuration item, e.g.
format=raw, vdev=xvda, access=rw, backendtype=phy, target=disksrc
Change the xl disk formatter to produce this syntax, which allows
target= to contain meta info needed to setup a network-based
disksrc (e.g. rbd, nbd, iscsi). For details on xl disk config
format, see $xen-src/docs/misc/xl-disk-configuration.txt
Update the disk config in the tests to use the formal syntax.
But add tests to ensure disks specified with the positional
parameter syntax are correctly converted to <disk> XML.
