Handle buffer pointer in LAP mode to avoid overflow

1. Always allocate at least MAX_GF_LENGTH_LAP + 1 stats buffers
even though lag-in-frames < MAX_GF_LENGTH_LAP.

2. Use compacting sliding window for stats buffers in LAP mode to avoid
out of boundary problems.

3. rest_frames in av1_get_second_pass_params is mistakenly calculated
in LAP mode. Correct the off by 1 error.
