The dropbox application has a feature called "LAN Sync" which works on
TCP & UDP port 17500. Marking this port as dropbox_port_t (instead of
the currently default unreserved_port_t) allows for more fine-grained
access control to this resource.

This changes the port declarations for cases where a type is used for
ports above and below 1024. The old code would give both the reserved
and unreserved port attribute. This new code only gives the reserved
port attribute.
Add a milter_port_t for use with inet sockets for communication
between milters and MTAs.
There are no defined ports with this type: admins are expected
to use semanage to specify the ports being used for milters.
The zabbix agent has its own dedicated port (10050) on which it needs to
bind/listen.
Also, the agent connects to the server so we add the zabbix_tcp_connect
interface (shamelessly copied from mysql_tcp_connect) and use it for the
zabbix_agent_t domain.
Update: structure interface calls more closely to styleguide

The zabbix server uses a dedicated port (10051). We define it and allow the
zabbix server to bind/listen on it.

Adds labeled IPSec policy to hadoop to control the remote processes that are allowed to connect to the cloud's services.
