2621d48f00 gnulib: delete all gnulib integration
This deletes all trace of gnulib from libvirt. We still
have the keycodemapdb submodule to deal with. The simple
solution taken was to update it when running autogen.sh.

Previously gnulib could auto-trigger refresh when running
'make' too. We could figure out a solution for this, but
with the pending meson rewrite it isn't worth worrying
about, given how infrequently keycodemapdb changes.

This sets the GLib event loop as the impl when calling
virEventRegisterDefaultImpl(). This remains a private
impl detail of libvirt, so applications must *NOT*

They should continue to use the libvirt-glib API

This follows the general principal that the libvirt public

to change the RPC client code to use GMainLoop. We don't
really want to use GIOChannel, but it provides the most
convenient way to do socket event watches with Windows
portability. The other alternative would be to use GSocket
but that is a much more complex change affecting libvirt

5de317b8e7 src: introduce helper API for creating GSource for socket
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.

dc0771cfa2 tools: rewrite interactive job monitoring logic
For long running jobs (save, managed save, dump & live migrate)
virsh runs a background thread for executing the job and then
has the main thread catch Ctrl-C for graceful shutdown, as well
as displaying progress info.

The monitoring code is written using poll, with a pipe used
to get the completion status from the thread. Using a pipe
and poll is problematic for Windows portability. This rewrites
the code to use a GMainLoop instance for monitoring stdin and
doing progress updates. The use of a pipe is entirely eliminated,
instead there is just a shared variable between both threads
containing the job completion status.

No mutex locking is used because the background thread writes
to the variable only when the main loop is still running,
while the foreground thread only reads it after the main loop
has exited.

s390-ccw-virtio-2.5) and without any guest CPU model configured fails
with

    CPU models are not available: KVM doesn't support CPU models

QEMU error. This is cause by libvirt using host-model CPU as the default
CPU based on QEMU reporting "host" CPU model as being the default one
(see commit v5.9.0-402-g24d8202294: qemu: Use host-model CPU on s390 by
default). However, even though both QEMU and KVM support CPU models on
s390 and QEMU can give us the host-model CPU, we can't use it with old
machine types which only support -cpu host.
