Modular DNS resolution

[Guilhem Lavaux]

Hi !

I would like to introduce in classpath a concept which used to be in 
kaffe but was recently removed because of the merging with classes from 
classpath: DNS solver modularity. Previously it was possible to specify 
to kaffe (using -Ddns.resolve=class or something like this). That used 
to give an advantage: use a native method (using e.g. gethostbyname) or 
a Java method to resolve internet name. The java method is already 
implemented and we can get a lot of other useful insights to resolved 
name than we can get with gethostbyname. As the code to add if fairly 
simple (add an interface and a if branch at class initialization), I 
think it can be added painlessly.

Anyway if you are furiously against it (;-)) just tell me so it can be 
discussed...

Cheers,
Guilhem.
