Update to junixsocket 1.4.

- Fixes InetSocketAddress.port issue with recent JDK implementations.
- some minor changes (build, library loading)
Fix issue #19: Native library fails to load on rhel4 32-bit when crosscompiled from rhel5 64-bit.

see https://code.google.com/p/junixsocket/issues/detail?id=19
Fix unit tests.

Some tests failed (at least on Linux) because
- the Server socket was left open after running a test
- we didn't check serverSocket.isClosed() directly where we should have
Issue #6	Cancelling accept() requests: Improve chance of breaking out of accept().

While I cannot reproduce the reported error anymore, this change will increase the chance that we break out of accept() upon serverSocket.close()
Remove stray System.out.println
