Tha problem was, that when we use hints tables, we do not check pages tree availability, but currently for receiving page object in CPDF_Document, the pages tree should be available anyway.

2017-09-28Fix infinite loop on form availability check.Artem Strygin
The problem was, that the CPDF_SyntaxParser read last block not from requested position. In this case It move down requested position to fill whole buffer. As result this additional data was not requested by DownloadHints. To fix this allow resize data buffer in CPDF_SyntaxParser, to store more small block, and always read from requsted position. Also add reading check into CPDF_Parser::LoadLinearizedMainXRefTable to prevent infinite loops.

2017-08-23Convert string Find methods to return an OptionalRyan Harrison
The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.
