09d64da3a4 Add some copyright and license terms, at Jordan's request. Note that
syscall.h just refers to another file for the copyright notice.

d7b7dcba41 Change the ioctls for procfs around a bit; in particular, whever possible,
change from

	ioctl(fd, PIOC<foo>, &i);

to

	ioctl(fd, PIOC<foo>, i);

This is going from the _IOW to _IO ioctl macro.  The kernel, procctl, and
truss must be in synch for it all to work (not doing so will get errors about
inappropriate ioctl's, fortunately).  Hopefully I didn't forget anything :).

20fa828fac Use the new PF_LINGER flag -- when this is set in a process' proc structure,
said process will not have its event mask cleared (and be restarted) on
the last close of a procfs/mem file for that pid.  This reduces the chance
that a truss-monitored process will be left hanging with these bits set
and nobody looking for it.

This is the least-tested change of all of these, I'm afraid.

fe41f30547 Set the close-on-exec flag in the child; otherwise, it eats up a
file descriptor that it shouldn't.

970649f9c9 First cut at printing out ioctl names intelligently. Note that this doesn't
handle linux ioctls (yet?).  This uses the mkioctl script from kdump,
bless its little heart.
