Package org.ops4j.pax.logging.spi.support

This package may be Private-Packaged by particular pax-logging backends (thus doing a copy), so common functionality (like implementation of LogReaderService) is kept in one place. This package should not be exported. Even default/fallback logger is here (to be Private-Packaged by backends), because there's no requirement to have singleton instance of DefaultServiceLog.
