Implement the qemu hooks for XML namespace data. This allows us to specify a qemu XML namespace, and then specify: <qemu:commandline> <qemu:arg value='arg'/> <qemu:env name='name' value='value'/> </qemu:commandline> In the domain XML. Changes since v1: - Change the <qemu:arg>arg</qemu:arg> XML to <qemu:arg value='arg'/> XML - Fix up some memory leaks in qemuDomainDefNamespaceParse - Rename num_extra and extra to num_args and args, respectively - Fixed up some error messages - Make sure to escape user-provided data in qemuDomainDefNamesapceFormatXML Signed-off-by: Chris Lalancette <clalance(a)redhat.com&gt;

Add the library entry point for the new virDomainQemuMonitorCommand() entry point.

Since we are adding a new "per-hypervisor" protocol, we make it so that the qemu remote protocol uses a new PROTOCOL and PROGRAM number. This allows us to easily distinguish it from the normal REMOTE protocol. This necessitates changing the proc in remote_message_header from a "remote_procedure" to an "unsigned", which should be the same size (and thus preserve the on-wire protocol).
