Convert libxl driver to Xen 4.2 

Based on a patch originally authored by Daniel De Graaf

  http://lists.xen.org/archives/html/xen-devel/2012-05/msg00565.html

This patch converts the Xen libxl driver to support only Xen >= 4.2.
Support for Xen 4.1 libxl is dropped since that version of libxl is
designated 'technology preview' only and is incompatible with Xen 4.2
libxl.  Additionally, the default toolstack in Xen 4.1 is still xend,
for which libvirt has a stable, functional driver.

<strong>libxl</strong>: Starting with Xen 4.2, the legacy XenD/xm
toolstack is deprecated in favor of libxl, also commonly called
libxenlight. libvirt supports this new Xen toolstack via the
libxl driver. If XenD is enabled, the legacy xen driver consisting
of the above mentioned channels will be used. If XenD is disabled,
the libxl driver will be used.
