Reenabled test unveiled a bug in socket.c when comparing socket
addresses.

I had to deactivate the tests in osl_SocketAddr.cxx
and osl_Socket2.cxx in makefile.mk. These tests failed:
osl_SocketAddr.cxx (SHL5TARGET) caused Segmentation fault.
osl_Socket2.cxx (SHL6TARGET) just failed with error 1.

I added the option SILENT_TEST in osl_Socket.cxx and in
sockethelper.hxx to allow tests without output
(t_print disabled).

These crash on NULL pointers, which they expect the API to handle properly.
It doesn't.

Interesting is that it fails a test that according to the API
docs should work (rtl_matH_doubleToString of 1.#INF returns 'INF'
instead of '1.#INF').
