Need to review maplegend.c mapscale.c and mapunion.c as well

@szekerest I have taken care of the ones in maplegend.c and mapscale.c . mapunion.c needs fixing also I would say, however I do not know the logic of that function to be able to do so myself. The code seems wrong if it isn't guaranteed that c->numlabels is equal to 0 before entering this function. Is this the case?

Hmmm... How'd I miss these originally. Probably wasn't compiling a kitchen sink build. Sorry about that... --Steve

There's a call to resetClassStyle() on the classObj which removes all labels, so we're fine to proceed. Last fix related to msGrowClassLabels in 8e62696. closing
