Functions NSS_CMSDigestedData_Encode_AfterData and

NSS_CMSDigestedData_Decode_AfterData
- Since NSS_CMSDigestContext_FinishSingle always destroys the context,
  regardless of whether it returns SECSuccess or SECFailure, these
  functions have been changed to always NULL out the context pointer
  after calling NSS_CMSDigestContext_FinishSingle, regardless of the
  outcome.
