[Bug classpath/22699] Net subsystem fixes

[gcc-bugzilla at gcc dot gnu dot org]

Various fixes for the net subsystem:
* errors thrown by InetSocketAddress are more explicit.
* prevent NullPointerException when doing a comparison (ala Sun)
(InetSocketAddress)
* InetSocketAddress.toString should build a string with the internal requested
hostname if that hostname cannot be solved.
* InetAddress:
      - new LOOPBACK_BITS static field to store localhost address.
      - IPV6 compatibility
      - added isAnyAddress and isLoopbackAddress
* NetworkInterface (optional but recommanded):
      - don't forget to load native library javanet
      - native call getRealNetworkInterfaces return  a Hashtable now instead of
a vector.

I commited parts of the patch to classpath and libgcj. I left IPv6
compatibility out because of total incompleteness. This will get merged with
libgcj soon.
I dont think its a good idea in NetworkInterface to use Hashtable instead of
Vector.
