2017-05-26Avoid dangling encrypt dict pointer in CPDF_ParserTom Sepez
CPDF_Parser::StartParse should release the current encrypt dict before trashing it by calling RebuildCrossRef() at cpdf_parser.cpp:195. This gives rise to the pattern that calls to ReleaseEncryptHandler() are followed by SetEncryptDict(nullptr), so just move the later into the former.

2017-05-23Make CPDF_ImageCacheEntry retain CPDF_ImageTom Sepez
CPDF_PageRenderCache::m_ImageCache is a map from streams to an image cache entry containing a clump of data associated with the stream. Oddly, the clump includes the stream key (which we already have in order to get to the clump), but worse doesn't ensure the existence of the CPDF_Image object which (maybe) owns the stream key in question. So replace the stream with a retained ptr to the image. Also renamed an unrelated member to avoid confusion with the CPDF_Object in play.

CFGAS_GEFonts are ref counted, and its a good thing since they are managed by at least three different font managers: CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these have a clear claim to ownership of the CFGAS_GEFont. CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and CXFA_PDFFontMgr, and they could each outlive the other. Thus the font needs to watch for destruction of either of its managers, so as to stop using it after its gone.
