allow in-place creation (for increased locality) of netlist classes. Main use is in truthtable class. - Remove PLIB_NAMESPACE macros. - Remove namespace macros. Use explicit namespace declarations. - Moved device definitions into cpp files. - Moved more device definitions into cpp files. - New prefix "nlid" for include files flags purely internal include files not to be leaked into userland. - Fix factory code.
