Eric Blake bc3f5f190e conf: consolidate disk def allocation 
A future patch wants to create disk definitions with non-zero
default contents; to avoid crashes, all callers that allocate
a disk definition should go through a common point.

I found allocation points by looking for any code that increments
ndisks, as well as any matches for ALLOC.*disk.  Most places that
modified ndisks were covered by the parse from XML to domain/device
definition by initial domain creation or device hotplug; I also
hand-checked all drivers that generate a device struct on the
fly during getXMLDesc.

* src/conf/domain_conf.h (virDomainDiskDefNew): New prototype.
* src/conf/domain_conf.c (virDomainDiskDefNew): New function.
(virDomainDiskDefParseXML): Use it.
* src/parallels/parallels_driver.c (parallelsAddHddInfo):
Likewise.
* src/qemu/qemu_command.c (qemuParseCommandLine): Likewise.
* src/vbox/vbox_tmpl.c (vboxDomainGetXMLDesc): Likewise.
* src/vmx/vmx.c (virVMXParseDisk): Likewise.
* src/xenxs/xen_sxpr.c (xenParseSxprDisks, xenParseSxpr):
Likewise.
* src/xenxs/xen_xm.c (xenParseXM): Likewise.
* src/libvirt_private.syms (domain_conf.h): Export it.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
