2018-08-17Rename CJS_Return to CJS_Result.Tom Sepez
"Return" is a verb, and "return" is a reserved-word at that, so avoid using it as part of a class name. Fully mechanical change apart from rename.

2018-08-07Speculative fix for null deref above ThrowNoDefaultPropertyExceptionTom Sepez
Avoid possibility of an unterminated string or nullptr by avoiding stringviews, since the non-view classes copy and always provide a suitable result. Always use %ls and widestrings in wprintf() variants, since that combination is consistent across our platforms (%s, %S, etc. have idiosyncracies).

This CL moves all ownership of nodes into a CXFA_NodeOwner class which CXFA_Document subclasses. The node owner always owns all nodes and is responsible for cleaning them up upon destruction. The destruction order is not guarenteed to be in tree order as nodes can be inserted and moved around the tree.
