Fixed openjpeg.c for proper initialization of codec context structures (dinfo in opj_create_compress() and opj_create_decompress(). Bug fix suggested by Andrey V. Kiselev 

Clean up of opj_aligned_malloc(), to just forgo the use of posix_memalign(), as apparently memalign() is what is working better for everyone. Patch by Callum.
