etc_changed, passwd & group

Ok.  I took another stab at this, cleaning up some more stuff and moving
(almost) everything into the pwdgrp class.  Hardly anything is marked
NO_COPY now.

I moved etc out of uinfo since, as I mentioned, I plan on using it for
more than just passwd/group stuff someday.  I renamed sawchange to
change_possible and made change_possible a tri-state where -1 means
definitely changed.

I think that I worked around the potential for a race by explicitly testing
any registered files prior to checking if the directory had changed.

And, I explicitly closed the file even in the error condition.

For the "Novell case", I explicitly check the creation time of the file
every time.  It may be slower but at least it makes cygwin behavior consistent
regardless of whether the FS.

I also a debug_printf showing how many lines were read in in pwdgrp::load
(I made all of the functions in pwdgrp into non-inline, hope Corinna doesn't
mind but I got tired of watching six files recompile every time I made a

I've got some more checks to run and then I'll checkin the current
sources and make YA snapshot -- the first to be deployed on the new

Once again, these are not trivial changes, but I think they are zeroing in
on something.  I am still not sure if the handle concept for the etc class
makes sense.  I may end up just going with a linked list of etc elements
