Introducing the new TPM-Direct API

This is a major change to the go-tpm library. It introduces the API that was proposed in 2022 as "TPMDirect", which maps TPM commands to Go structs instead of funcs, allowing greater composability. Stay tuned for more information about this change and how to get started.

If you want to update to this release of go-tpm, you don't have to rewrite all your code! You can start using the new API at your leisure. Simply use the old API at its new path by changing from github.com/google/go-tpm/tpm2 to github.com/google/go-tpm/legacy/tpm2 in your code's import statements:

import github.com/google/go-tpm/tpm2

to

import github.com/google/go-tpm/legacy/tpm2

Interstitial 0.3.1 
TPM2: Added CertifyEx and encodeCertifyEx (#211)

* TPM2: Added CertifyEx and encodeCertifyEx which differ from Certify and encodeCertify in that they take the scheme to be used as an additional argument.

Signed-off-by: El Mostafa IDRASSI <[email protected]>

* Fixed typo

* Rename parentAuth and ownerAuth to objectAuth and signerAuth respectively.

Signed-off-by: El Mostafa IDRASSI <[email protected]>

* Update Certify documentation to explain it makes use of the hardcoded signing scheme {AlgRSASSA, AlgSHA256}.

* Pack AlgNull with no following hash alg in case of AlgNull scheme, and add TODO comment.

* Comment formatting and other requested changes.

Signed-off-by: El Mostafa IDRASSI <[email protected]>

* Replace all occurrences of tpmtSigScheme with SigScheme.
Add CertifyEx tests for both RSASSA/SHA256 and ALG_NULL cases.

* Better implementation of TestCertifyEx with all cases.

Signed-off-by: El Mostafa IDRASSI <[email protected]>

* Requested changes implemented.

Fix CVE-2020-8918 
Fix TPM 1.2 migration (#195)

* Fix issue with TPM 1.2 migration auth (#1)

Fix some TPM 1.2-specific issues related to key migration and testing:

- 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

* Delete extraneous file
