tpm: extend TPM emulator with state migration support Extend the TPM emulator backend device with state migration support. The external TPM emulator 'swtpm' provides a protocol over its control channel to retrieve its state blobs. We implement functions for getting and setting the different state blobs. In case the setting of the state blobs fails, we return a negative errno code to fail the start of the VM. Since we have an external TPM emulator, we need to make sure that we do not migrate the state for as long as it is busy processing a request. We need to wait for notification that the request has completed processing.
