Fix some TPM 1.2-specific issues related to key migration and testing, along with CVE-2020-8918:

  • A bug in CreateWrapKey that uses an incorrect key to encrypt a key's migrationAuth value
  • Addition of AuthorizeMigrationKey and CreateMigrationBlob command functions to enable testing of migration auth bug fix
  • A bug fix in TakeOwnership that prevented successful authorization of the command
  • A session leak in a couple of TPM 1.2 tests (TestOIAP and TestOSAP)
  • Improvements to the TPM 1.2 tests to allow execution on a TPM that needs to be started up
  • Initial effort at documentation for running the TPM 1.2 tests against the IBM simulator
