It simply needs to be just one parameter table.  The starting point is
to get the two existing tables in sync (they are already for
service-specific parameters).

We could start by using another #include to bring in the common
portion. 

I'm not in favour of things like FLAG_SAMBA3 or FLAG_SAMBA4 - instead,
some parameters may simply only be used in some parts of the codebase.
This happens already, some things only impact on nmbd, or winbindd, and
this is just an extension of that.
