Enable accepting file names with `-´ symbol .Modification getopt.c 

Rsiz profile name generation to be STD_RSIZ for profiles which are not DCI compliant.Modification in image_to_j2k.c
Renamed convert_progression_order to j2k_convert_progression_order. Modification j2k.c
Calculation of number of tile part in each tile in j2k_calculate_tp. Modification j2k.c
j2k_setup_encoder to set bit rate limitation for digital cinema compliance with quality option. Modification in j2k.c
Equation to check multiple tile precincts. Modification pi.c
array size generation of pi->include in pi_initialise_encode().Modification in pi.c
Modification in pi_create_encode for tile part generation.Modification in pi.c
In tcd_rateallocate a variable stable_threshold which holds the valid threshold value. This is used to avoid error in case of a wrong threshold value in the last iteration. Modification in tcd.c.
