[AGENT++] Vb::get_value(...) and IP-address

[Jochen Katz]

Hi,

you hit a bug in address classes.

The "valid" flag for a Address object created this way is "false"

>             ipa[1] = buffer[1];

These set-functions don't change the "valid" flag, as they cannot know 
when the address is valid.

So an invalid address is added to the Vb, which therefore hasn't a valid 
value and returns a zero string for get_value().

The solution would be to define that an Address created like above 
defaults to "0.0.0.0" which is a "valid" address. Additionally the valid 
flag should be set to true whenever operator[] is called.

Any objections against these two changes? If yes, provide a better 
solution ;-)
