Initial support for Bundle-NativeCode

[thomas.diesler]

Initial support for navtive code is provided by the OSGiBundleNativeCodeDeployer

http://fisheye.jboss.org/browse/JBossOSGi/projects/runtime/framework/trunk/src/main/java/org/jboss/osgi/framework/deployers/OSGiBundleNativeCodeDeployer.java?r=98041

This works such that the deployer adds the library mapping to the OSGiClassLoaderPolicy

      // Add the native library mapping to the OSGiClassLoaderPolicy
      OSGiClassLoaderPolicy policy = unit.getAttachment(ClassLoaderPolicy.class);
      policy.addLibraryMapping(libname, nativeFileCopy);

Which is then used by the OSGiBundleClassLoader

public class OSGiBundleClassLoader extends BaseClassLoader
{
   ...

   @Override
   protected String findLibrary(String libname)
   {
      String libraryPath = null;

      if (osgiPolicy != null)
         libraryPath = osgiPolicy.findLibrary(libname);

      if (libraryPath == null)
         libraryPath = super.findLibrary(libname);

      return libraryPath;
   }
}

This solution currently relies on OSGiClassLoaderSystem that needs to create the OSGiBundleClassLoader

public class OSGiClassLoaderSystem extends ClassLoaderSystem
{
   ...

   @Override
   protected BaseClassLoader createClassLoader(ClassLoaderPolicy policy)
   {
      return new OSGiBundleClassLoader(policy);
   }
}

A better solution would be to support the notion of native library mapping in ClassLoadingMetaData, ClassLoaderPolicy and BaseClassLoader directly.
