Creates a new client session to the designated server with PSK credentials @param ctx The CoAP context. @param local_if Address of local interface. It is recommended to use NULL to let the operating system choose a suitable local interface. If an address is specified, the port number should be zero, which means that a free port is automatically selected. @param server The server's address. If the port number is zero, the default port for the protocol will be used. @param proto Protocol. @param identity PSK client identity @param key PSK shared key @param key_len PSK shared key length

@return A new CoAP session or NULL if failed. Call coap_session_release to free.
