[DGD] Kernel library updates

[Raymond Jennings]

New updates pushed to git://github.org/shentino/kernellib

Changes:

* General work on resources

I backed out a change allowing system resources to be removed.  My first
attempt wound up making kernel code unclear and in some cases deceptive by
implying resources where none existed.

For now, they're back in and cannot be removed.

Also, there is now stricter checking on resource manipulation.  Now,
attempting to manipulate a resource that doesn't exist, or for a user that
doesn't exist, now causes an error.

* Patch function to restore system resources.

I added a patch function to reinstate any system resources that were
removed in the past.  Just recompile the kernel library, then call
RSRCD->patch() from a System object.

* Ownerless /usr directories are now accounted as Ecru

I noticed that it was in fact possible to have a /usr directory
corresponding to a user that does not exist in rsrcd.  Those directories
are now accounted as Ecru.

* Recompilation of an object now does not require object resource

Since recompiling an object doesn't actually affect how many objects exist,
it now no longer requires resource checks.

* Creation of kernel objects is now exempt from resource checks

Blocking the compilation or cloning of a kernel object can actually cause
complications if for example the kernel library is being rebuilt and kernel
inheritables cannot be compiled.

Previously only telnet connections, binary connections, and resource
objects were exempt, now the entire kernel is.

* Admin wiztool is now exempt from resource limits

Makes it possible to recover from accidentally killing the admin with
resource limits.

* Simplify swap rate reporting in status command

The old method was a bit more complicated than it needed to be, and could
actually get messed up formatting if the swap rate got really high.

* Don't pass infinite rlimits to user code

There were a few places where an internal usage of infinite rlimits was
passed back out to non kernel code.  One example was logging out a user
when a connection was closed.
