* autoload.cc: Add LoadDLLinitfunc for iphlpapi.dll.
Add LoadDLLfuncEx statements for GetIfTable@12 and GetIpAddrTable@12.
* fhandler_socket.cc (fhandler_socket::ioctl): Move variable
definitions to the beginning of the function to allow better debugging.
Add handling for SIOCGIFHWADDR, SIOCGIFMETRIC and SIOCGIFMTU.
* net.cc: Include iphlpapi.h.
(get_2k_ifconf): Rewritten. Uses IP Helper API now.
(get_nt_ifconf): Add handling for SIOCGIFHWADDR, SIOCGIFMETRIC
and SIOCGIFMTU.
(get_95_ifconf): Ditto. Renamed from `get_9x_ifconf'.
(get_ifconf): Name loopback `lo' instead of `lo0' as in Linux.
Add handling for SIOCGIFHWADDR, SIOCGIFMETRIC and SIOCGIFMTU.
Call `get_95_ifconf' only on Windows 95, `get_nt_ifconf' only
on Windows NT < Service Pack 3, `get_2k_ifconf otherwise.
* include/asm/socket.h: Add defines for SIOCGIFHWADDR, SIOCGIFMETRIC
and SIOCGIFMTU.
* include/cygwin/if.h: Add `ifr_hwaddr', `ifr_metric' and `ifr_mtu'.
(struct ifreq): Add `ifru_hwaddr'.
