This sets the GLib event loop as the impl when calling
virEventRegisterDefaultImpl(). This remains a private
impl detail of libvirt, so applications must *NOT*
assume that a call to virEventRegisterDefaultImpl()
results in a GLib based event loop.
They should continue to use the libvirt-glib API
gvir_event_register() if they explicitly want to guarantee
a GLib event loop.
This follows the general principal that the libvirt public
API should not expose the fact that GLib is being used
internally.

The libvirt-glib project has provided a GMainContext based
event loop impl for applications. This imports it and sets
it up for use by libvirt as the primary event loop. This
remains a private impl detail of libvirt.
IOW, applications must *NOT* assume that a call to
"virEventRegisterDefaultImpl" results in a GLib based
event loop. They should continue to use the libvirt-glib
API gvir_event_register() if they explicitly want to
guarantee a GLib event loop.

We need to be able to create event loop watches using the
GSource API for sockets. GIOChannel is able todo this, but
we don't want to use the GIOChannel APIs for reading/writing,
and testing shows just using its GSource APIs is unreliable
on Windows.
This patch thus creates a standalone helper API for creating
a GSource for a socket file descriptor. This impl is derived
from code in QEMU's io/channel-watch.c file that was written
by myself & Paolo Bonzini & thus under Red Hat copyright.

A large part of the virCommand code is still built on
WIN32, despite the fact that the core fork() & execve()
functions are not available. So despite succesfully
building most of the code, at runtime the APIs are
none the less unusuable. With the elimination of GNULIB
many of the APIs being used in this code no longer have
portability wrappers/shims for Windows.
Rather than try to add portability wrappers, or do tests
for each individual function, it is clearer to conditionalize
nearly all of the code using #ifdef WIN32.
