This is a debug tool used to detect bitstream error. On encoder side, it pushes
each bit and probability into a queue before the bit is written into the
Arithmetic coder. On decoder side, whenever a bit is read out from the
Arithmetic coder, it pops up the reference bit and probability from the queue as
well. If the two results do not match, this debug tool will report an error.
This tool can be used to pin down the bitstream error precisely. By combining
gdb's backtrace method, we can detect which module causes the bitstream error.

There was a bug in the original set up for RATE_FACTOR_LEVELS, which
results that rate_factor_deltas for GF_ARF_STD is 2.00, instead of the
intentional value of 1.75, whereas for KF_STD is 0.00, instead of the
intentional value of 2.00.

Nevertheless, if simply fixing the bug as in the first patch, the RD
performance unexpectedly dropped by 0.143% in Avg bitrate using
Overall PSNR, especially for following sequences in lowres:

bridge_close_cif: dropped by 1.468%
container_cif: dropped by 2.140%
husky_cif: dropped by 0.826%
motherdaughter_cif: dropped by 0.798%
rasehorses_240p: dropped by 0.805%
students_cif: dropped by 1.411%

This indicates that we should boost up the value for GF_ARF_STD from
1.75 to at least to 2.00. After doing so, while still keeps 2.00 for
KF_STD, the new patch achieves a small gain of 0.15% for the baseline,
and a smaller gain of 0.06% for the experiment of ext-refs. Most
sequences keep the similar RD performance in lowres, except for the
following ones that obtain a bigger gain:

(1) Baseline:
container_cif: 1.628%
students_cif: 1.015%

(2) ext-refs
tennis_sif: 1.248%
