wtc%netscape.com 83b9358446 Bug 186586: If at NSS shutdown there are still certs in the cert caches,
cause NSS shutdown and the next NSS initialization to fail but do not
destroy the cert caches (and the crypto context and trust domain containing
them) to avoid a crash if the NSS client destroys the certs later.  New
error codes needed to be added to indicate the failure of NSS shutdown and
NSS initialization due to this cause.
