Changes in internal API: * Every route attribute must be defined as struct ea_class somewhere. * Registration of route attributes known at startup must be done by ea_register_init() from protocol build functions. * Every attribute has now its symbol registered in a global symbol table defined as SYM_ATTRIBUTE * All attribute ID's are dynamically allocated. * Attribute value custom formatting hook is defined in the ea_class. * Attribute names are the same for display and filters, always prefixed by protocol name. Also added some unit testing code for filters with route attributes.
