Maybe, but the question is more generic: *should* a QgsFeatureId have
a default value ? In that case maybe we could change its definition
from a typedef to a class and define such default value ? OR keep
it a typedef and consider 0 (the current typedefe'd type default)
as meaning NULL (can we ensure no *real* feature would ever have a
fid value of 0, from every provider?).
