Reland "Avoid duplicate data buffering in CPDF_SyntaxParser::ReadStream()."
This is a reland of 77f15f7883638a4ced131d74c053af10a5970ce9
Original change's description:
> 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.
