[PATCH] iphlpapi: Implement if_nametoindex.

[Stefan Dösinger]

libtorrent (and game patchers based on it) call this function when they
detect an ipv6-capable internet connection.

I have placed the implementation in iphlpapi_main.c instead of ifenum.c
because ifenum.c right now contains no exported function.
