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.

2018-04-23Disable JavaScript entirely if no JSPlatform passed by embedder.Tom Sepez
Allows run-time selection of whether to permit JS inside PDF. Previously, this was a link-time decision only. This requires a little more caution before we decide that we have the CJS_Runtime, and not the CJS_RuntimeStub in a few casts. Adds a kDisableJavaScript option to the form fill embeddertests. Adds a --disable-javascript flag to the pdfium_test executable. Also adds a --disable-xfa flag while we're at it.
