Change license to LGPL.
...
- 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!

Use the same coeff cost calculation for all rd modes.

Add cu_info* as parameter to reconstruction functions.
...
- This is required so these functions can be used for searching. When NULL
is given they take the CU from LCU struct as they did previously.

Unify signature for transform functions.

Add --rd=3 mode and enable searching of intra depth 0.
...
- 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.

Remove chroma mode "36".
...
- It's an unnecessary chore to handle this special case everywhere (it means
chroma_mode == intra_mode). Better just to use the actual mode.

benefit should be quite small anyway.

Refactor picture to remove hidden dependency between slice and tiles
...
picture.type -> encoder_state->global->pictype
picture.slicetype -> encoder_state->global->slicetype
picture.slice_sao_luma_flag -> 1 (was constant)
picture.slice_sao_chroma_flag -> 1 (was constant)
This may be changed later. For now it's better to avoid having slice related stuff in picture.
