LSPL draft

The LibreSilicon Public License, LSPL for short, should:

1. be based on the AGPL
2. cover software, HDL code, schematics, layouts and netlists
3. allow dynamic linking of libraries in closed-source projects, like in the LGPL
4. extend the dynamic linking policy from the LGPL to IP-cores licensed under the LSPL
5. make use of the legal protection of topographies (layout designs) of semiconductor products
