More post Pcbnew NETLIST_READER change clean up.

* Fix both legacy and s-expression netlist readers when footprints are
  assigned in the netlist.
* Add some helper functions to NETLIST for detecting when footprints are set
  or not set and when they have been changed while loading the .cmp file.
* Rename a few functions to improve their readability.
