2017-06-27Changed the return type for annotation APIsJane Liu
Before: When returning FPDF_ANNOTATION, the APIs would take in a FPDF_ANNTOATION* and write the handle of the annotation to it, while returning a boolean as status. This CL: This CL changes the APIs to directly return FPDF_ANNOTATION, which would be null on failure. Also adds more null checks within the annotation APIs.

2017-06-22Minor change to AP generation logicJane Liu
Current behavior: Our CPVT_GenerateAP::Generate*AP() functions do not get called as long as the annotation dictionary has an "AP" entry. Problem: We always need the "N" entry in AP dictionary to display an annotation. Even though the spec requires "AP" dictionary to have an "N" entry for normal mode appearance, in case of a malformed pdf with "AP" but without "N" in "AP", we won't be able to display the annotation at all. Fix: Always check if "AP" has "N" entry to decide whether AP needs to be generated. If not, then we still need to generate AP, and add to the AP dictionary under the key "N".
