P4Libraries::Shutdown()

Clean up static initializations. Must be called with the same arguments as P4Libraries.Initialize().

For example, in sample/p4api.cc the Initialize arguments are P4LIBRARIES_INIT_ALL, &e:

P4Libraries::Initialize( P4LIBRARIES_INIT_ALL, &e ); so the call to Shutdown uses those same arguments:

P4Libraries::Shutdown( P4LIBRARIES_INIT_ALL, &e );
