getifaddrs: Return pointer to extended interface info in ifa_data member

Browse Source 
According to https://cygwin.com/ml/cygwin/2016-03/msg00124.html it's a
problem to collect friendlyname info using AF_INET6 sockets.  Fix problem
by exposing additional hardware info for all collected interfaces via the
pointer in the ifaddrs::ifa_data member.

	* include/ifaddrs.h (struct ifaddrs_hwdata): Define as struct of
	not yet exposed members of struct ifall, defined in net.cc.
	* net.cc (struct ifall): Replace hardware dta members with struct
	ifaddrs_hwdata.  Accommodate throughout.
	(get_ifs): Let ifaddrs ifa_data member point to ifall::ifa_hwdata
	member.
