unix: add ifreq and ifreqData helpers for Linux ifreq is difficult to use in Go due to the union field in particular. This situation is made worse due to the need to comply with Go's unsafe.Pointer rules. This CL generates the raw ifreq type and also adds an ifreqData type of the same size which is specialized for use with unsafe.Pointer. We also replace the existing ifreqEthtool (which was not padded to the correct size) with the new APIs and add a test to verify that IoctlGetEthtoolDrvinfo functions properly by checking the name of the driver for each network interface. Future uses of ifreq in package unix can expand upon this type with additional getter and setter methods to deal with the unsafe casts to and from the union byte array. We may also consider exporting ifreq and ifreqData if necessary.
