This is necessary for finding ChromaOffsetL0/ChromaOffsetL1
prediction weight table values with out using any hard coding.
Fixme: We don't have parser API for sps_range_extension, so
assumed zero value for high_precision_offsets_enabled_flag.

HACK: This is a work-around to identify some main profile streams having wrong profile_idc.
There are some wrongly encoded main profile streams(eg: ENTP_C_LG_3.bin) which doesn't
have any of the profile_idc values mentioned in Annex-A, instead general_profile_idc
has been set as zero and having general_profile_compatibility_flag[general_profile_idc]
is TRUE. Assuming them as MAIN profile for now.

We are calculating the dpb size based on max_dec_pic_buffering.
But if there are more than one temporal sublayers, we are supposed
to use the max_dec_pic_buffering[max_sub_layers_minus] for dpb
size calculation (Assuming HighestTid as max_sub_layers_minus).
Sample streams: TSCL_A_VIDYO_5.bin, TSCL_B_VIDYO_4.bin

Decoding process for reference picture list construction needs to be
invoked only for P and B slice and the value for slice_type of dependent slice
segment should be taken from the previous independent slice segment header
of the same pic.

Based up on the value of uniform_spacing_flag in Picture Parameter Set,
the tile column width and tile row height should be calculated.
Equations: 6-1, 6-2
Tiled video Descriptions: 7.3.2.3, 7.4.3.3
-- Set NoRaslOutputFlag based on EOS and EOB Nal units
-- Fix PicOutputFlag setting for RASL picture
-- Fix prev_poc_lsb/prev_poc_msb calculation
-- Drop the RASL frames if NoRaslOutputFlag is TRUE for the associated IRAP picture
-- Fixed couple of crashes and added cosmetics
