Digital cinema compliance for 4K chosen by "-cinema4K" option. Modification in image_to_j2k.c. 

Bit rate limitation for each color component. Modification in image_to_j2k.c, t2.c.
Modified and tested Progression order change "-POC" option. Modification in image_to_j2k.c, j2k.c, pi.c.
Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c.
Structure T2_MODE. This tells if the t2_encode_packets() is called during Threshold calculation or in Final pass. Modification in j2k.h, tcd.c
