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!

Unify signature for transform functions.
...
- Some used block, coeff and some src, dst. Now all signatures are const input
and non-const output.

Move optimizations to their own compilation units according to target.
...
- This is necessary in order to compile AVX intrinsics correctly in
Visual Studio. Having everything in their own units should also make
compiling normal C code with optimizations on easier.
- For now the makefile still relies on GCC __target__ attribute for compiling
intrinsics.
