* @brief A class which provides methods to create and use UDP sockets.
*
* Addresses are of type @ref OFSocketAddress. You can use the current thread's
* @ref OFDNSResolver to create an address for a host / port pair,
* @ref OFSocketAddressString to get the IP address string for an address and
* @ref OFSocketAddressPort to get the port for an address. If you want to
* compare two addresses, you can use
* @ref OFEqualSocketAddress and you can use @ref OFSocketAddressHash to get a
* hash to use in e.g. @ref OFMapTable.
*
* @warning Even though the OFCopying protocol is implemented, it does *not*
* return an independent copy of the socket, but instead retains it.
* This is so that the socket can be used as a key for a dictionary,
* so context can be associated with a socket. Using a socket in more
* than one thread at the same time is not thread-safe, even if copy
