improved the non-block check a lot: 

* several tests ALWAYS failed due to bad test programs
* the IoctlSocket() test now is linked on test as it could otherwise compile
  fine on many systems that doesn't support it
* added a test for the BeOS way of doing non-blocking sockets (based on a
  patch from Shard)
