alived 0.3.0

alived is a simple daemon and client for sending keepalive messages. The server keeps a list of hostname to IP address, useful for when a remote DHCP client changes IP addresses.
The whole idea is to have a machine send its current IP address to a server. This is because I hate it when my machine reboots and looses its DHCP assigned addressed while Im away from it.
To run it, install the alive daemon (alived) on a server. It can be invoked with alived to run in a terminal, or alived -d to run as a daemon.
The client (alive) should be setup to start during the startup of the system. On the command line you need to pass the name of your host and the IP or hostname of the server running the daemon.
alookup is used to query a server for a specific name, returning its last known IP address and the time the server last heard from the host.
Enhancements:
- Modified alived, alive and alookup to use getopt_long() and follow the GNU standards more closely.
