* FUNCTION: pkix_CacheCert_Lookup
* DESCRIPTION:
*
* Look up Cert Hash Table for a cached item based on "store" and Subject in
* "certSelParams" as the hash keys and returns values Certs in "pCerts".
* If there isn't an item to match the key, a PKIX_FALSE is returned at
* "pFound". The item's cache time is verified with "testDate". If out-dated,
* this item is removed and PKIX_FALSE is returned at "pFound".
* This hashtable is maintained in the following ways:
* 1) When creating the hashtable, maximum bucket size can be specified (0 for
* unlimited). If items in a bucket reaches its full size, an new addition
* will trigger the removal of the old as FIFO sequence.
* 2) A PKIX_PL_Date created with current time offset by constant
* CACHE_ITEM_PERIOD_SECONDS is attached to each item in the Hash Table.
* If the CertStore this Cert is from is a trusted one, the cache period is
* shorter so cache can be updated more frequently.
* When an item is retrieved, this date is compared against "testDate" for
* validity. If comparison indicates this item is expired, the item is
* removed from the bucket.
*
* PARAMETERS:
* "store"
* Address of CertStore as key to retrieve this CertChain. Must be
* non-NULL.
* "certSelParams"
* Address of ComCertSelParams that its subject is used as key to retrieve
* this CertChain. Must be non-NULL.
* "testDate"
* Address of PKIX_PL_Date for verifying time cache validity.
* Must be non-NULL. If testDate is NULL, this cache item won't be out
* dated.
* "pFound"
* Address of KPKIX_Boolean indicating valid data is found.
* Must be non-NULL.
* "pCerts"
* Address PKIX_List where the CertChain will be stored. Must be no-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 an Error Error if the function fails in a non-fatal way.
* Returns a Fatal Error if the function fails in an unrecoverable way.
