- Changed behaviour of net_recv(), ssl_fetch_input() and ssl_read(). net_recv() now returns 0 on EOF instead of POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function. ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received after the handshake.

- Network functions now return POLARSSL_ERR_NET_WANT_READ or POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous POLARSSL_ERR_NET_TRY_AGAIN
