Introduce maven plugin that can check that a native lib can be used w… (#10) Motivation: In the past we messed up released native libs as we did compile on the wrong GLIBC version. This can lead to situations when its not possible anymore to use the native libs an a specific system. We should be able to verify that all works as expected during the build / release process. Modifications: - Make netty-build a multi maven module project - Move all existing code to the common module - Introduce glibccheck-maven-plugin that can be used to validate that a native lib will be usable with a specific GLIBC version Result: Provide maven plugin that can be used to verify linking of native lib to correct GLIBC version
