SLF4J-574: Add full OSGi headers, especially "uses" clauses

Fixes: https://jira.qos.ch/browse/SLF4J-574

This uses the BND tool, via org.apache.felix to generate
the MANIFEST.MF to be fully compliant with OSGi.
Compared to using just the maven-jar-plugin to create
the MANIFEST.MF the uses clauses are added to the
Export-Package
