- It's so widely used that there isn't really need to emphasize that
it's the encoders state. Also, it isn't really the encoders state,
but encoding jobs state.
- Everyone who has contributed code to the project has been asked to license
their contributions under LPGL and they have agreed.
- COPYING file changed to say LGPLv2.1 instead of GPLv2.
- GPL changed to LGPL in the header of every single file that a header and
header added to the few that were missing one.
- Also.. Happy new year!
- There is some stuff from sign hiding left intermingled with rdoq code,
but I don't want to change the code too before testing that I didn't
break anything.
- Remove cu_info.intra[].cost and bitcost as unnecessary.
- Add luma_mode_bits to complement chroma_mode_bits and remove
intra_pred_ratecost as unneccessary. Difference is that intra_pred_ratecost
was more coarse and included chroma mode with the assumption that it would
be the same as chroma.
- intra_build_reference_border was overflowing at depth 0 because it uses
arrays just large enough to accommodate 32x32 transforms, which is the
biggest transform.
- For similar reasons search_intra_rough doesn't work at depth 0.
- The --rd=3 mode tries all modes with transform search. It also works without
rough search so it was used to test depth 0 search. If --rd=3 is not on intra
split at depth 0 is not searched for.

- Because cost was calculated even though there were no coefficients, these
very good modes were less likely to be selected.
- Added assert to encode_coeff_nxn to avoid these problems in the future.
- It's meant for checking if there are any coefficients, but we don't use it
and it's annoying to remember to initialize it and pass it around. The
benefit should be quite small anyway.
The relation between coefficients positions and coefficient group positions
was a big confusing due to the use of 16x16 diagonal coefficient mappings
also as coefficient group mappings.
- Moved all coefficient group mappings to their own const arrays and added
a new array the select the correct coefficient group mapping. This removes
special cases for 8x8 and 32x32 transform sizes.
- Removed all coefficient group mapping initialization from init_sig_last_scan.
- Removed 128x128 and 64x64 from regular coefficient group array as those
transform sizes don't exist anymore in HEVC.
