2017-05-18Break linkage from CPDFXA_DocEnvironment to IJS_EventContext.Tom Sepez
CPDFXFA_DocEnvionment is part of the heirarchy of objects owned by the embedder under its FPDF_Document object. IJS_EventContext is part of the hierarchy of objects owned by the embedder under its FPDF_FormHandle object. The FPDF_Document must outlive the FPDF_FormHandle, so there is a lifetime inversion with the m_pJSEventContext member. No matter, event contexts are transient and allocated in a stack-based manner as control bounces from C++ to JS and vice versa, and keeping a persistent one seems wrong. So make it only as needed.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.
