[GObjectInstrospection] How to tell scanner the default invoker

[Daniel Espinosa <esodan gmail com>]

I'm working on Bug #585351, but the first path modify some virtual methods in some GObjects, breaking the ABI for 4.x series, then I need to know how tell the scanner how to find the default invoker for a virtual method. The message from the scanner is, pj:

warning: Interface 'DataModel' virtual function 'i_get_n_rows' has no known invoker

libgda/gda-data-model.c

defines for the GdaDataModel object virtual methods with an "i_" prefix, and the scanner trys to find a gda_data_model_i_get_n_rows function as a default invoker, but the correct function's name is gda_data_model_get_n_rows. My first try modify the virtual method from 'i_get_n_rows' to 'get_n_rows', this works but breaks ABI in LibGDA 4.x series then is rejected for now.

Then how modify or add this methods to the gir file?
