1d06027c69 DO NOT MERGE Fixed bug in the case of resolution change. 
Modified the way i4_header_decoded in decoder context
is used, to ensure that resolution change is detected
even if PPS has not been decoded.

Bug: 35583675
Test: ran POC, no longer hangs

0b23c81c3d Decoder: Fixed initialization of first_slice_in_pic 
To handle some errors, first_slice_in_pic was being set to 2.
This is now cleaned up and first_slice_in_pic is set to 1 only once per pic.
This will ensure picture level initializations are done only once even in case
of error clips

69b5191865 Decoder: Add supported width check for MBaff streams 
In case of MBAff streams, decoder processes two rows at a time,
this limits maximum supported width to 1920 for MBAff streams.
