For further simplifying virt-p2v's GTK API usage, require the GLIB2 and
GTK3 versions that RHEL7 provides.
The MIN_REQUIRED=<version> macros elicit warnings if we use an API that
was already deprecated in said version of the given library.
The MAX_ALLOWED=<version> macros make sure we don't unwittingly use an API
that was introduced after our required minimum version.
(GDK is a layer below GTK, so using the GDK_VERSION_* macros ensures both
GDK and GTK API compatibility.)

Optional.
If the D-Bus low level C API is available, virt-p2v can send a D-Bus
message to logind to inhibit power saving (sleep, suspend, etc) during
P2V conversions.
If this API is not available at build time, then very long conversions
might be interrupted if the physical machine goes to sleep.
