Since the Xen driver was changed to only execute inside libvirtd,
there is no scenario in which it will be opened from a non-privileged
context. Thus all the code dealing with opening the sub-drivers can
be simplified to assume that they are always privileged.

This is a follow up patch of commit f9ce7dad, it modifies all
the files which declare the copyright like "See COPYING.LIB for
the License of this software" to use the detailed/consistent one.

And deserts the outdated comments like:

 * libvirt-qemu.h:
 * Summary: qemu specific interfaces
 * Description: Provides the interfaces of the libvirt library to handle
 *              qemu specific methods
 *
 * Copy:  Copyright (C) 2010, 2012 Red Hat, Inc.

Uses the more compact style like:

 * libvirt-qemu.h: Interfaces specific for QEMU/KVM driver

Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.

virInitialize() → xenRegister() → xenhypervisorInit() determines the
version of the Hypervisor. This breaks xencapstest when building as root
on a dom0 system, since xenHypervisorBuildCapabilities() adds the "hap"
and "viridian" features based on the detected version.

Add an optional parameter to xenhypervisorInit() to disable automatic
detection of the Hypervisor version. The passed in arguments are used
instead.

Calling virInitialize() → xenRegister() → xenhypervisorInit() directly
opens a connection to the Xen Hypervisor, which breaks some unit tests.

Move all static variables into a struct to make it easier to override
them when testing.
