[Libguestfs] [p2v PATCH 0/2] restrict supported GLIB2 and GTK3 versions
Remove GTK3 compat code that is not needed on RHEL7+. Incorporate suggestions from Rich and Daniel in the subthread at <https://listman.redhat.com/archives/libguestfs/2022-September/029940.html>. Do not remove "gui-gtk3-compat.h" altogether; I expect we may have to add in new compat stuff in the future, and having to redo the infrastructure for that is not a great prospect.

[Libguestfs] [p2v PATCH 1/2] require GLIB2 >= 2.56 and GTK3 >= 3.22; enhance API compatibility
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.)

If this API is not available at build time, then very long conversions
might be interrupted if the physical machine goes to sleep.
