f1e173049e avcodec/jpeg2000: Remove CBLK limit 
This also reduces the amount of memory needed
Fixes Ticket4672

The new code seems slightly faster as well, probably due to better cache usage

4e926fb969 avcodec/jpeg2000: Move L band scaling from the 9/7f wavelet to quantization stage 
This reduces the number of operations
Its not done for 9/7i as that would overflow thanks to JPEG2000 allowing
32 decomposition levels

1c495b0bf6 avcodec/jpeg2000: Move gainb handling into the quantization code 
thats how the specification defines it, this also improves numerical
accuracy of the integer wavelet implementation. It otherwise should
be equivalent, in case of overflows this can be reverted.
