Subject: lwip: Use the right error type.

Use lwip's err_t as return type for functions called from lwip
and error_t for functions called from the translator.

* lwip/io-ops.c: Include <errno.h>
	* as is not being included for other headers anymore.
* lwip/lwip-util.h: Likewise.
* lwip/port/include/netif/hurdethif.h:
	* Include <errno.h>
	* Change the return type of the init function to err_t.
* lwip/port/include/netif/hurdloopif.h: Liekwise.
* lwip/port/include/netif/hurdtunif.h: Likewise.
* lwip/port/include/netif/ifcommon.h: Likewise.
* lwip/port/netif/ifcommon.c: Likewise.
* lwip/port/netif/hurdloopif.c:
	* Include <errno.h>
	* Change output function return type to err_t.
        * Return lwip's err_t codes.
* lwip/port/netif/hurdethif.c:
	* Include <errno.h>
	* Change init function return type to err_t.
	* Change output function return type to err_t.
	* Return lwip's err_t codes.
* lwip/port/netif/hurdtunif.c: Likewise.
