gresolver: Mark GResolver as an abstract class

Browse Source 
It only works through its virtual methods, so while it could be
instantiated before (and this is technically an API break), any instance
of it would previously have crashed as soon as any of its methods were
called anyway.

If anybody has any problems with this ABI break, please make them known
during the 2.51 unstable development cycle and it can be reverted.
