Change license

Currently the library contains the following licenses:

• GNU Lesser General Public 2.1
• Apache License, Version 2.0

The latter license is used only in few files, LGPL in many places. Some files have neither.
Should we move to GPL v3?
Any comments...

Would this be appropiate way to list all contributos, and/or perhaps there are more?
They could be listed on the top of each file, after the license text.
