====================
various compat ioctl fixes

Back a long time ago, I already fixed a few of these by passing
the size of the struct ifreq to do_sock_ioctl(). However, Robert
found more cases, and now it won't be as simple because we'd have
to pass that down all the way to e.g. bond_do_ioctl() which isn't
really feasible.

Therefore, restore the old code.

While looking at why SIOCGIFNAME was broken, I realized that Al
had removed that case - which had been handled in an explicit
separate function - as well, and looking through his work at the
time I saw that bond ioctls were also affected by the erroneous
removal.

I've restored SIOCGIFNAME and bond ioctls by going through the
(now renamed) dev_ifsioc() instead of reintroducing their own
helper functions, which I hope is correct but have only tested
with SIOCGIFNAME.
