Minor tweak to the file upload hooks. The MULTIPART_EVENT_FORMDATA event

was only triggering when an input filter was applied.  This simple change
makes the event also trigger when no filter is applied.  The newlength
pointer is set to NULL to let a downstream module differentiate between
the two cases.
