**  SMAR_INIT_MAP_LFL -- initialize SMAR map lookup flags (aliases/lum/mt)
**	(after reading configuration)
**
**	Parameters:
**		smar_ctx -- SMAR context
**		lfl_conf -- lookup flags from configuration
**		plflags -- (pointer to) lookup flags for smar_ctx (input/output)
**				note: this must be set to the initial value for lflags!
**
**	Returns:
**		SM_SUCCESS
**
**	Can we do this simpler, e.g., a 1-1 mapping?
