ioctl translation preliminary patch

[Dan Jacobowitz]

All right, I wrote up some code to do this - I've been running it for a
few days now and haven't had a single problem, so I'll submit it.  The
symbol versioning is not the way I want it to be, although it makes
only the tiniest performance difference; is it possible to specify
symbol versions in a syscalls.list file?  I wanted __syscall_ioctl to
be the ioctl@GLIBC_2.0.  Otherwise, of course, sticking a simple
function in ioctl.c would achieve the same end, but I was too far into
the compile when I figured that out to try it.  It could use a little
polishing, but it's all there.
