Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard. This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter) 

Warning: The output image size is now reduced when discarding resolutions !

* [FOD] Changed the way the image structure is allocated when the decoding parameters include some resolutions to discard.

* [FOD] Patch from Callum Lewick. Clean up of j2klib.h for the aligned malloc stuff.
It makes it work right with mingw, as _mm_malloc() isn't a macro, attempts to pave the way to using cmake to check for this stuff and combines a patch from Dana Fagerstrom at Sun that makes it use memalign() on Solaris
