PR canonical#357 migrated the tpm2 code to using the new tpm2.TPMDevice abstraction for opening TPM connections. The go-tpm2 package contains some other deprecated APIs, and in some cases, entire packages have been deprecated (crypto, templates, util). These have been replaced by alternative APIs, and ithe util package, which was a bit of a dumping ground for APIs that had nowhere else to go, has been split into more focused packages. This ports secboot to using updated APIs. It's just a straight port for now - we may want to refactor some code to make better use of these APIs in future PRs.

PR #357 migrated the tpm2 code to using the new tpm2.TPMDevice abstraction for opening TPM connections.
The go-tpm2 package contains some other deprecated APIs, and in some cases, entire sub-packages have been deprecated (crypto, templates, util). These have been replaced by alternative APIs, and the util package, which was a bit of a dumping ground for APIs that had nowhere else to go, has been split into more focused packages.
This ports secboot to using updated APIs. It's just a straight port for now - we may want to refactor some code to make better use of these APIs in future PRs - particularly those in the
policyutilsub-package, something that will allow us to create keys with arbitrary policies without having to change the key data format for tpm2 keys (see issue #350).
