This patch series takes the long road on the way to adding support
for Xen's max_grant_frames to libvirt. Patch1 adds a new 'xenbus'
controller type that supports a maxGrantFrames attribute.
maxGrantFrames describes the maximum IO buffer space (or DMA space)
available in the xenbus controller for use by connected paravirtual
devices.
Patch2 adds a xenbus controller to the domXML in post-parse callback
if one is not explicitly specified, with downside of requiring touching
all test files.
Patch3 adds support for max grant frames in the libxl driver and a
test to check the libxl domain config generator. Patch4 adds support
for the setting on the domXML<->native config converter and also
includes a test.

conf: Add a new 'xenbus' controller type
libxl: Add implicit xenbus controller
