OSGi changes

All the published artifacts are OSGi bundles or fragments.

This release introduces a change in the bundle symbolic names to allow them to function as JPMS module name: all hyphens - present in the bundle names of previous releases were replaced by dots ..

JPMS changes

All the published artifacts have been migrated from automatic modules to named JPMS modules. All packages marked as private in the Javadoc are not exported.

The module name of four bridges (log4j-slf4j-impl, log4j-slf4j2-impl, log4j-to-jul and log4j-to-slf4j) have been changed to adhere to the same convention as the OSGi bundle names.
