SecureSocket: add OpenSSL locking.

This shoiuld make OpenSSL more thread safe and help with the random
network related crashes in Web+ (and anything else using SecureSocket
with more than one thread).

Added experimental version of a Socket API with SSL support.

* Each class has a Socket() method to retrieve the underlaying file descriptor
to be able to do the more advanced stuff, if necessary.
* A server socket is yet missing, but the rest is pretty much covered.
