...and xen_backend.h to xen-legacy-backend.h
Rather than attempting to convert the existing backend infrastructure to
be QOM compliant (which would be hard to do in an incremental fashion),
subsequent patches will introduce a completely new framework for Xen PV
backends. Hence it is necessary to re-name parts of existing code to avoid
name clashes. The re-named 'legacy' infrastructure will be removed once all
backends have been ported to the new framework.
This patch is purely cosmetic. No functional change.

Most list head structs need not be given a name. In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed. In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct. So clean up everything, not giving a
name except in the rare case where it is necessary.

Create a qdev plugged to the xen-sysbus for each new backend device.
This device can be used as a parent for all needed devices of that
backend. The id of the new device will be "xen-<type>-<dev>" with
<type> being the xen backend type (e.g. "qdisk") and <dev> the xen
backend number of the type under which it is to be found in xenstore.

Olaf Hering reported a build failure due to an undefined reference
to 'qemu_log_vprintf'. Explicitely including qemu/log.h seems to
fix the issue.
