2018-06-27Rework of loading of CPDF_Document.Artem Strygin
Improve CPDF_Document interface. Fix relationship between CPDF_Document and CPDF_Parser.

2018-05-25Make CPDF_Page retainable.Tom Sepez
Small step to reducing the differences between XFA and non-XFA. We still use the RetainPtr pretty much as if it were an unique_ptr, in that we're not yet caching pages and handing out multiple pointers to the same page in the non-XFA case. The one change is in page view cleanup, where we no longer need a boolean and can take (sufficient) page ownership with a RetainPtr. Tidy up some document.h -> page.h -> document.h circular inclusion while we're at it. NOTE: Wait for imminent branch to pass before landing. We'll want this to bake a while.
