Subo:
- red con dos mejoras:
  1) las conexiones quedan identificadas por su IP y por su puerto.
  2) cuando una conexión se cierra, sus paquetes salientes se descartarán.
- tests actualizados para utilizar el nuevo API de la red. Las modificaciones
  son menores, pero obligan a revisar todo el código que usa la red.
- paquetes de red estructurados de acuerdo a la memoria.

Seguiré haciendo modificaciones en la infraestructura para que utilice
la versión más reciente de este módulo.
