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!

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.

chroma_mode == intra_mode). Better just to use the actual mode.

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.
