[RFC, PATCH 0/7] net, compat_ioctl: move handlers to net/socket.c

This cleans up some of the socket ioctl handling by moving it
from fs/compat_ioctl.c to net/socket.c. The code is still untested,
so this is an RFC for now. If you're happy with it, I'll do some
testing to see if everything still works.

This series is a prerequisite for cleaning up the rest of
compat_ioctl.c, saving some 30kb of kernel memory in the end.

The first four patches are probably worthwhile independently,
because they fix some bugs in compat_ioctl handling.
There is some obvious conflict with the ATM patch I sent
independently today. That one should probably be worked out
first.
