2018-06-20Re-work some more c_str() usage.Tom Sepez
Many of these are converting ByteString => c_str => ByteStringView, since the ByteStringView ctor is implicit. This is unfortunate, since that involves a strlen() which the ByteString already knows if we use AsStringView() instead. This changed one test result where we can now return the string "\0" instead of "" -- since strlen no longer eats the NUL. This seems consistent, say, with String.fromCharCode().

Precursor to removing some more v8::Context slot dependency. There's a cost to maintaining the set of observers, but since these objects are tied to V8 lifetimes, not C++ lifetimes, we want to be very wary of the document going away unexpectedly.

2018-05-30Make CPDF_Document cache CPDF_PagesTom Sepez
We cache pages not by page number, which can bounce around as pages are inserted or removed, but by page dictionary's object number. Since the page may be created under one function and used under another, we can't take the shortcut of not instantiating a render cache nor not parsing the page.

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.
