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.
