fb0597574d libxl: Add implicit xenbus controller 
All Xen domains have a xenbus device. Implicitly add one if not
already explicitly specified in the domain config.

dffe584aa4 libxl: add support for memballoon device 
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.

b90c4b5f50 xlconfigtests: use qemu-xen in all test data files 
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.

96b21fb0ec Fix tests to include video ram size 
My commit 3e42867 started filling out the video size in post-parse,
but did not adjust the tests.

4b35a7155a tests: fix xen-related tests 
My commit 6879be4 moved the addition of the implicit video device
from the XML parser to the PostParse function, but did not regenerate
all the tests.

6604a3dd9f xenconfig: support xl<->xml conversion of rbd disk devices 
The target= setting in xl disk configuration can be used to encode
meta info that is meaningful to a backend. Leverage this fact to
support qdisk network disk types such as rbd. E.g. <disk> config
such as

   <disk type='network' device='disk'>
     <driver name='qemu' type='raw'/>
     <source protocol='rbd' name='pool/image'>
       <host name='mon1.example.org' port='6321'/>
       <host name='mon2.example.org' port='6322'/>
       <host name='mon3.example.org' port='6322'/>
     </source>
     <target dev='hdb' bus='ide'/>
     <address type='drive' controller='0' bus='0' target='0' unit='1'/>
   </disk>

can be converted to the following xl config (and vice versa)

  disk = [ "format=raw,vdev=hdb,access=rw,backendtype=qdisk,
            target=rbd:pool/image:auth_supported=none:mon_host=mon1.example.org\\:6321\\;mon2.example.org\\:6322\\;mon3.example.org\\:6322"
         ]

Note that in xl disk config, a literal backslash in target= must
be escaped with a backslash. Conversion of <auth> config is not
handled in this patch, but can be done in a follow-up patch.

Also add a test for the conversions.
