/*
* This is a wrapper around type
* CERTValInParam is a nested input parameter type for CERT_PKIXVerifyCert.
* The values inside this type depend on application preferences,
* as a consequence it's expensive to construct this object.
* (and we shall avoid to access prefs from secondary threads anyway).
* We want to create an instance of that input type once, and use as long as possible.
* Every time the preferences change, we will create a new default object.
*
* A race is possible between "verification function is active and object in use"
* and "must switch to new defaults".
*
* The global default object may be replaced at any time with a new object.
* The contents of inner CERTValInParam are supposed to be stable (const).
*
* In order to protect against the race, we use a reference counted wrapper.
* Each user of a foreign nsCERTValInParamWrapper object
* (e.g. the current global default object)
* must use nsRefPtr<nsCERTValInParamWrapper> = other-object
* prior to calling CERT_PKIXVerifyCert.
*
* This guarantees the object will still be alive after the call,
* and if the default object has been replaced in the meantime,
* the reference counter will go to zero, and the old default
* object will get destroyed automatically.
