Changes

The ''targetSlot'' and ''sourceSlot'' parameters could be slots that are simply looked up, or additional databases opened with SECMOD_OpenUserDB(). In order for the merge to be successful, targetSlot must support all the intersection of the following object list and the token objects in the sourceSlot (CKO_CERTIFICATE, CKO_PUBLIC_KEY, CKO_PRIVATE_KEY, CKO_SECRET_KEY, CKO_NSS_TRUST, CKO_NSS_CRL, CKO_NSS_SMIME). The source Slot must also have extractable keys or the merge will fail (sensitive keys are OK, as long as the source slot supports PBE's if it contains private keys).
