Clang has previously had trouble with G_DEFINE_AUTOPTR_CLEANUP_FUNC
generated code, thinking it was unused. We turn off -Wunused-function
to avoid tripping up on that with CLang.
New Clang has started having trouble with g_autoptr now too. In usage
scenarios where the variable is set, but never again read, it thinks
it is unused not realizing the destructor has useful side effects.
For this we have to skip -Wunused-but-set-variable on CLang.

When accessing libvirtd over a SSH tunnel, the remote driver needs a way
to proxy the SSH input/output stream to a suitable libvirt daemon. This
is currently done by spawning netcat, pointing it to the libvirtd socket
path. This is problematic for a number of reasons:
- The socket path varies according to the --prefix chosen at build
time. The remote client is seeing the local prefix, but what we
need is the remote prefix
- The socket path varies according to remote env variables, such as
the XDG_RUNTIME_DIR location. Again we see the local XDG_RUNTIME_DIR
value, but what we need is the remote value (if any)
- The remote driver doesn't know whether it must connect to the legacy
libvirtd or the modular daemons, so must always assume legacy
libvirtd for back-compat. This means we'll always end up using the
virtproxyd daemon adding an extra hop in the RPC layer.
- We can not able to autospawn the libvirtd daemon for session mode
access
To address these problems this patch introduces the 'virtd-ssh-helper'
program which takes the URI for the remote driver as a CLI parameter.
It then figures out which daemon to connect to and its socket path,
using the same code that the remote driver client would on the remote
host's build of libvirt.

Until now we've tried to report errors from the test monitor code by

work well in cases when the monitor logic does not detect failures or
has fallback code. Additionally there isn't much use for continuing the
test execution after first failure as in most cases the test data will
be misaligned and all other calls will fail as well.
To make the errors more obvious this patch moves away from reporting
them via the simulated monitor to reporting them to stderr and
exit()ing afterwards. While this might be less convenient
when developing tests it actually makes failures in the test suite
really obvious and doesn't require any opt-in from the tests themselves.

The previous "QEMU shim" proof of concept was taking an approach of only
caring about initial spawning of the QEMU process. It was then
registered with the libvirtd daemon who took over management of it. The
intent was that later libvirtd would be refactored so that the shim
retained control over the QEMU monitor and libvirt just forwarded APIs
to each shim as needed. This forwarding of APIs would require quite alot
of significant refactoring of libvirtd to achieve.
This impl thus takes a quite different approach, explicitly deciding to
keep the VMs completely separate from those seen & managed by libvirtd.
Instead it uses the new "qemu:///embed" URI scheme to embed the entire
QEMU driver in the shim, running with a custom root directory.
Once the driver is initialization, the shim starts a VM and then waits
to shutdown automatically when QEMU shuts down, or should kill QEMU if
it is terminated itself. This ought to use the AUTO_DESTROY feature but
that is not yet available in embedded mode, so we rely on installing a
few signal handlers to gracefully kill QEMU. This isn't reliable if
we crash of course, but you can restart with the same root dir.
Note this program does not expose any way to manage the QEMU process,
since there's no RPC interface enabled. It merely starts the VM and
cleans up when the guest shuts down at the end. This program is
installed to /usr/bin/virt-qemu-run enabling direct use by end users.
Most use cases will probably want to integrate the concept directly
into their respective application codebases. This standalone binary
serves as a nice demo though, and also provides a way to measure
performance of the startup process quite simply.

Some syntax check rules validate usage of headers provided
by gnulib. We want to validate these only against the gnulib
modules we've chosen to use, not all modules, since we're
trying to eliminate them.

The GLib g_size_checked_mul() function is not quite the
same signature, and gives compiler warnings due to not
correctly casting from gsize to guint64/32. Implementing
a replacement for INT_MULTIPLY_OVERFLOW is easy enough
to do ourselves.

When using GNULIB with Winsock, libvirt will never see the normal HANDLE
objects, instead GNULIB guarantees that libvirt gets a C runtime file
descriptor. The GNULIB poll impl also expects to get C runtime file
descriptors rather than HANDLE objects. Document this behaviour so that
it is clear to applications providing event loop implementations if they
need Windows portability.

As part of a goal to eliminate Perl from libvirt build tools,
rewrite the group-qemu-caps.pl tool in Python.
This was a straight conversion, manually going line-by-line to
change the syntax from Perl to Python. Thus the overall structure
of the file and approach is the same.

The original inline shell and perl code was completely
unintelligible. The new python code is a manual conversion
that attempts todo basically the same thing.
