* contrib/entitynorm: * use fewer entities, browsers don't support all either. * update to generate code for new entconv. * no need for configure, use just a simple Makefile (it is an internal tool) libclamav/entconv.c, hashtab.c, htmlnorm.c: * don't allocate memory for each entity_norm call. * don't touch length of mmaped area (bb #785) * update htmlnorm to use new entity_norm
