* [FOD] Changed the OpenJPEG library interface to enable users to access information regarding the codestream (also called codestream index).
This index is usefull for all applications requiring to have a scalable acces to the codestream (like JPIP applications, ...)
Currently, this information is only available when encoding an image.

* [FOD] Fixed wrong destructors called in openjpeg.c
* [FOD] Fixed bug in j2k_decode_jpt_stream
