ef807fde69 Fix integer overflows while intializing reference lists 
Instead of looping through all poc/pic numbers with an increment
of 1, loop through only valid poc/pic numbers after sorting them.
This prevents integer overflows when poc/pic number is INT32_MIN or
INT32_MAX

This also fixes a timeout issue seen when integer sanitizers are
not enabled

cbcd2846fa Decoder: Fixed overflow in refernce list creation. 
Since the maximum value of long term index is 255,
the loop control variable needs to be 32 bit.
