the socket API yields wrong Error codes for connect(). The usage of EALREADY and EISCONN are not handled as expected by the BSD socket API.

in err.h, introduce new LWIP internal error code ERR_ALREADY
in sockets.c add mapping of EISCONN to the err_to_errno_table array
in api_msg in function do_connect() give out correct errors ERR_ISCONN and ERR_ALREADY in the correct cases
