gobject introspection wants a capital letter for the gir file
- See https://gi.readthedocs.io/en/latest/buildsystems/autotoolsintegration.html: "Namespace of the gir, first letter capital, rest should be lower case"
- This will help vapigen to find correct namespaces
- Update m4/introspection.m4 from upstream
- Panel now requires libxfce4util 4.15.6
