2017-04-07Cleanup string passing in core/fpdf*Tom Sepez
Return strings where possible. Add missing consts to strings passed by ref. Convert non-const cases to pointers. Rename a few methods to be clearer.

2017-03-22Fix ASSERT in CPDF_Data_AvailNicolas Pena
If ParseIndirectObjectAt fails, the replaced object will be null. So we can't ASSERT the output of ValidatePage.

2016-12-07Refcount all the IFX_ stream classes all the time.tsepez
We can remove a lot of "bOwnsStream" logic in the process. Always pass these by const reference, in case the called method wants to hang on to the stream (one exception is where we stick a raw pointer into a void* slot in a context from another layer).
