As RHEL provides a stable tool chain, we don't have to worry about
frequent changes in reported compiler warnings (which prevents us from
enabling -Werror unconditionally).

Libssh2 isn't reliable enough to support the libvirt transport using it.
The problems include mishandling of "known_hosts" files that may confuse
users.
If libapparmor-devel happens to be installed when building the
RPM, it will failed due to unlisted virt-aa-helper in %files.
Add support for apparmor in the spec, so that we can explicitly
turn it on/off, defaulting to off in all distros. This causes
--without-apparmor to be given to configure, preventing the
build failures if the user happens to have libapparmor-devel
present.

The python/tests directory contains a number of so called
"tests" for the python API. These are all hardcoded to
look for Xen and cannot be run in any automated fashion,
and no one is ever manually running them. Given that they
don't meaningully contribute to the test coverage, delete
them.
For some reason these tests were also copied into the
filesystem as part of 'make install'. The change to the
RPM in commit 3347a42032
caused a build failure, since it removed the code which
deleted these installed tests.

Mingw *printf is a moving target; newer mingw now provides a version
of asprintf() that fails to understand %lld:

../../../../examples/domain-events/events-c/event-test.c:270:18: error: unknown conversion type character 'l' in format [-Werror=format=]

But since our examples already admitted that they were hacking around
a mingw deficiency, it is easier to just use printf() directly, coupled
with <inttypes.h> macros, for a more portable work-around.

Commit a2619962 introduced virFilePrintf to work around the fact
that gnulib doesn't (yet) provide guarantees about fprintf() vs.
%z, which in turn causes all sorts of mingw compilation errors:

../../tests/testutils.c:101:9: error: unknown conversion type character 'z' in format [-Werror=format=]
fprintf(stderr, "%3zu) %-60s ", testCounter, name);

Rather than s/fprintf/virFilePrintf/ (and reformatting loads of
lines) across multiple files, it's easier to just hack the entire
testsuite to take advantage of our helper function.

The VIR_DOMAIN_PAUSED_GUEST_PANICKED constant is badly named,
leaking the QEMU event name. Elsewhere in the API we use
'CRASHED' rather than 'PANICKED', and the addition of 'GUEST'
is redundant since all events are guest related.
Thus rename it to VIR_DOMAIN_PAUSED_CRASHED, which matches
with VIR_DOMAIN_RUNNING_CRASHED and VIR_DOMAIN_EVENT_CRASHED.
It was added in commit 14e7e0ae8d
which post-dates v1.1.0, so is safe to rename before 1.1.1

The VIR_DOMAIN_SHUTDOWN_CRASHED state constant does not appear
to be used in the QEMU code anyway. It also doesn't make much
(any) sense, since the 'shutdown' state is a transient state
between 'running' and 'shutoff' and when a guest crashes, it
does not end up in a 'shutdown' state, only 'shutoff'.
It was added in commit 14e7e0ae8d
which post-dates v1.1.0, so is safe to remove before 1.1.1

The way we were casting small (<32bit) integers was broken

Current automake enables parallel test by default, which means test
details are only logged in test-suite.log and not printed to stderr.
This patch makes test failures directly visible in RPM build logs even
when parallel tests are turned on.

that other .c files hit the mingw header pollution from the

File hasn't been really touched for 7 years. And with recent rawhide
changes it contributed to an RPM build failure. Let's drop it.
This also removes installation of a libvirt-python doc dir, so drop
handling of it from the RPM spec.
When the legacy Xen driver probes with a NULL URI, and
finds itself running on Xen, it will set conn->uri. A
little bit later though it checks to see if libxl support
exists, and if so declines the driver. This leaves the
conn->uri set to 'xen:///', so if libxl also declines
it, it prevents probing of the QEMU driver.
Once a driver has set the conn->uri, it must *never*
decline an open request. So we must move the libxl
check earlier

Decrementing it when it was already 0 causes an invalid free

fails and virNetworkDNSHostDefClear gets called twice.
virNetworkForwardDefClear left the number untouched even if it
freed all the elements.
The outbound/@peak is ignored (since QoS was introduced). This is due to
kernel limitation of know allowing ingress filters to have peak just
average rate. However, we should document this limitation to not confuse
users.
Interestingly, we had <code>floor<code> ... </code>outbound</code> which
results in much larger block of text to be written in code style that
intended.
