[DGD] Kernel Library, Version 1.5.4

[Raymond Jennings]

Changes since 1.5.3:

* Infinite rlimits are no longer passed to userobj->logout when a
connection is closed.

* It is no longer an error to remove or add a resource or user that no
longer/already exists.  Manipulating a non existent resource or user is
still an error though, and removing a system resource remains forbidden for
now.

* With indexed resources, 0 is now a valid index in typechecking mode 2 (as
it seems to be intended)

* The check for LWOs being used as resource indexes has been removed from
RSRCOBJ as I just noticed API_RSRC already catches it.

* General ability to reset resources.

At first this was intended to help reconcile inconsistencies possibly
introduced by code and api changes in the past, but it turned into a
performance optimization in some cases.

* SYSTEM code can now query an object's indexed resources directly.

This is useful if you need to audit the resource management.  Also goes
with the previously noted change.
