2018-04-27Avoid potential duplicate unique_ptr to CPDF_Document from CPDFXA_Context.Tom Sepez
Should FPDFDocumentFromCPDFDocument() be called several times under XFA, we may WrapUnique() the document several times. So cache a pointer back from CPDF_Document to CPDFXFA_Context to avoid this. Because of layering, introduce a placeholder type CPDF_Document::Extension. This is actually the first step in some larger XFA ownership cleanup, but makes a nice standalone CL around the one particular issue.
