    _______________________________________________________

Details:

LWIP_HOOK_IP4_ROUTE() is called (if defined) at the beginning of the
ip4_route() function.

Maybe this should be moved down to after we check for a match to our
configured netifs, but before we check for the default router netif.

This way, the hook function doesn't need to duplicate the checks for local
subnet routing.

This only applies to LWIP_HOOK_IP4_ROUTE and not to LWIP_HOOK_IP4_ROUTE_SRC
