fix POC computation with several temporal layers
fixed definition of long-term picture when checking whether MVs should be scaled
fix check for taking B0 reference
remove debugging code
provide a fast path for banded SAO when no PCM and transquant_bypass are used
precompute actual CTB size in SAO
factor out common code to run SAO faster
simplify SAO edgeIdx computation by reordering the saoOffsetVal[] array
remove obsolet code from deblocking
add sao tasks (incomplete)
fix uninitialized values with long-term references
Merge branch 'LTRPSPS_A-undef-fix'
parallelized SAO
fast exit when SAO is completely switched off
SAO registers its thread_tasks now in image_unit
deblocking registers its thread_tasks in image_unit
made SAO input/output variable
copy arbitrary ranges of image lines
SAO runs parallel to deblocking
