         * qpid/sys/Shlib.h, .cpp: Portable shared library abstraction.
          - Shlib: load, unload, getSymbol
          - AutoShlib: unload in destructor.
         * qpid/sys/apr/Shlib.cpp sys/posix/Shlib.cpp: APR/Posix impls

         * qpid/sys/Module.h: Reimplemented Module in terms of AutoShlib.
         * qpid/Plugin.cpp, .h: Removed dlopen - use Shlib instead.

         * qpid/broker/Broker.cpp: Added missing #include "qpid/log/Statement.h"
         * tests/Shlib.cpp, shlibtest.cpp: Unit test
