* FUNCTION: pkix_PolicyChecker_Initialize
* DESCRIPTION:
*
* Creates and initializes a PolicyChecker, using the List pointed to
* by "initialPolicies" for the user-initial-policy-set, the Boolean value
* of "policyQualifiersRejected" for the policyQualifiersRejected parameter,
* the Boolean value of "initialPolicyMappingInhibit" for the
* inhibitPolicyMappings parameter, the Boolean value of
* "initialExplicitPolicy" for the initialExplicitPolicy parameter, the
* Boolean value of "initialAnyPolicyInhibit" for the inhibitAnyPolicy
* parameter, and the UInt32 value of "numCerts" as the number of
* certificates in the chain; and stores the Checker at "pChecker".
*
* PARAMETERS:
* "initialPolicies"
* Address of List of OIDs comprising the user-initial-policy-set; the List
* may be empty or NULL
* "policyQualifiersRejected"
* Boolean value of the policyQualifiersRejected parameter
* "initialPolicyMappingInhibit"
* Boolean value of the inhibitPolicyMappings parameter
* "initialExplicitPolicy"
* Boolean value of the initialExplicitPolicy parameter
* "initialAnyPolicyInhibit"
* Boolean value of the inhibitAnyPolicy parameter
* "numCerts"
* Number of certificates in the chain to be validated
* "pChecker"
* Address to store the created PolicyChecker. Must be non-NULL.
* "plContext"
* Platform-specific context pointer.
* THREAD SAFETY:
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
* RETURNS:
* Returns NULL if the function succeeds
* Returns a CertChainChecker Error if the functions fails in a non-fatal way
* Returns a Fatal Error if the function fails in an unrecoverable way
