This syscall allows to bind socket to specified file descriptor.
Descriptor can be gained by simple open with O_PATH flag.
Socket node can be created by sys_mknod().

i386 uses socketcalls... perhaps it shouldn't (socketcalls are pretty
much an abomination), but for socketcall-based architectures this really
should be a socketcall.
Thanks, Peter. I'll rework this.
Don't you also need fconnect()? Or is that simply handled by allowing
open() without O_PATH?
Yes, I need it.
If this approach will be accepted, then I'll send one more patch set for
fconnect.
