Avoid duplicate data buffering in CPDF_SyntaxParser::ReadStream().
Allow sub-streams created from an IFX_SeekableReadStream to provide
stream data without copying memory.
The data will only reside in the top-level stream.
For example:
For file
http://www.major-landrover.ru/upload/attachments/f/9/f96aab07dab04ae89c8a509ec1ef2b31.pdf
(18 Mb)
The memory usage is reduced by ~13 Mb.
