BC change

[Jakub Stachowski]

Hello,

Is it acceptable at this point to make BIC change to 
kdelibs/dnssd/ServiceBase.h ? I just want to add d-pointer (unused for now) 
to class to avoid breaking stuff during further development for kde 3.5 
(interested can check http://arch.hypair.net/TODO for details. of course 
comments and advice will be very appreciated). I know that d-pointer should 
be there from beginning but looks like i have forgotten about this one class. 
It is new in 3.4 so no current users will be hurt.
