This patch updates the iscsi layer to automatically pick a 'unique'
initiator-name based on the name of the vm in case the user has not set an
explicit iqn-name to use.
Create a new function qemu_get_vm_name() that returns the name of the VM, if
specified.
This way we c

The patch adds the driver to interface with the iscsi library.
The following patch adds a new block driver to QEMU/KVM for iSCSI.
This utilizes the userspace client library for iscsi at
https://github.com/sahlberg/libiscsi and will link with this library if
available.
This allows using iSCSI resources with QEMU/KVM without making them visible to
