compat: add struct compat_ifreq etc to compat.h
In order to move socket ioctl conversion code into multiple places in the socket code, we need a common defintion of the data structures it uses. Also change the name from ifreq32 to compat_ifreq to follow the naming convention for compat.h Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
