Add ioctl(SIOCGIFxxx) support (#197)

Browse source 
- SIOCGIFCONFIG: reads and enumerate all the network interfaces
- SIOCGIFADDR: reads network address for a given interface
- SIOCGIFFLAGS: reads network flags for a given interface
- SIOCGIFNETMASK: reads network netmask for a given interface
- SIOCGIFBRDADDR: reads network broadcast address for a given interface
- SIOCGIFDSTADDR: reads peer destination address for a given
  interface (not supported for Windows)

This change defines Linux ABI structs for the above interfaces and adds
polyfills to ensure they behave consistently on XNU and Windows.
