Mark Young 24373f2d98 Add loader policy statements
Define expected behavior for a well-behaved loader, layers, and drivers.
This has been reviewed with other companies so that when issues arise,
it is easy to clearly communicate where one of the components has failed
to properly behave.

Add warnings/errors in the loader output when cases of policy that can
be detected are noticed.
