David Zeuthen c3371efcaa Bug 624546 – Modification of GDBusMessage in filter function 
Rework filter functions as per

 https://bugzilla.gnome.org/show_bug.cgi?id=624546#c8

This commit breaks ABI. However, this ABI break affects only
applications using filter functions. The only known user of is dconf.
