socket: system getaddrinfo on Windows

Browse source 
* ext/socket/extconf.rb: use system getaddrinfo, getnameinfo, and
  freeaddrinfo on Windows if they are provided.  they conflict
  with addrinfo.h and cannot compile.  conftest.exe linked against
  msvcr90.dll segfaults when invoked in extconf.rb for unknown
  reason, and failed to check them.
