This is a respin to update several patches based on review feedback

General cover letter:

This patch updates the trusted key code to export keys in the ASN.1
format used by current TPM key tools (openssl_tpm2_engine and
openconnect).  It also simplifies the use of policy with keys because
the ASN.1 format is designed to carry a description of how to
construct the policy, with the result that simple policies (like
authorization and PCR locking) can now be constructed and used in the
kernel, bringing the TPM 2.0 policy use into line with how TPM 1.2
works.

The key format is designed to be compatible with our two openssl
engine implementations as well as with the format used by openconnect.
I've added seal/unseal to my engine so I can use it for
interoperability testing and I'll later use this for sealed symmetric
keys via engine:
