It's possible to create a stream of length 0 in a PDF document.
Currently the code will early exit and return a nullptr. This causes
issues when you want to print the given PDF as the FPDF_ImportPages code
ends up only generating up to the zero length object.
This CL allows creating streams with length 0 and updates the PDF saving
code to output a blank stream.

Freetype can get to values larger than 0x10FFFF, but our current implementation

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.

The test, as written, is only correct for the non-xfa case, where
the FPDF_Document opaque type is equivalent to the CPDF_Document.
Under XFA, however, there is another layer of indirection that
the test harness needs to respect.
Sorry, I missed this the first time around when I signed off
on the CL that introduced this test.

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.

tests for other OS will be added in a followup.
The ToUnicode works by defining the PDF charcodes as equal to the glyph indices
and assuming that the freetype charcodes given by FXFT_Get_Next_Char are in
fact the unicode values.
