autogenerate a minimal NULL value sequence for unknown pointer types This

Browse Source 
* gentest.py testapi.c: autogenerate a minimal NULL value sequence
  for unknown pointer types
* HTMLparser.c SAX2.c chvalid.c encoding.c entities.c parser.c
  parserInternals.c relaxng.c valid.c xmlIO.c xmlreader.c
  xmlsave.c xmlschemas.c xmlschemastypes.c xmlstring.c xpath.c
  xpointer.c: This uncovered an impressive amount of entry points
  not checking for NULL pointers when they ought to, closing all
  the open gaps.
