fe18375850 Fix resolution change within a decode call. 
If resolution changes within a decode call,due to multiple
sps, the decoder hangs as the the application will
give the same data again in the next decode call. This
results in a hang. Fixed this by flaging an error,
when sps/resoultion changes within a process call.

Bug: 38487564
Test: ran POC on patched O-based system w/o hanging

f9d3f9af8f Initializing reference list for every P/B slice. 
Reference list needs to be initialized for every P/B
slice, to ensure colocated picture always points to a
valid picture buffer, even in the case of error.

e98bd1f5a0 Decoder: Aligned pi1_left_pred_mode[8] in _DecStruct definition 
This array is sometimes accessed as two WORD32 variables.
On platforms that do not support unaligned load/stores, this needs
to be aligned to 4 byte boundary.

Bug: 33073518
Test: Tested with -fsanitize=alignment enabled on avcdec
