core: add macros to handle setter functions

Add macros to handle full function set functions in qPref

Remark: the function name is fixed to be "set_<name>" where name is
identical to the variable in struct preferences

This is not our standard naming, but is consistent with struct
preferences (that also use different name schemes).
