autogenerate a minimal NULL value sequence for unknown pointer types This
* 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.
