Extend the tpm library with support for single authorized (AUTH1) commands as specified in the TCG Main Specification 1.2. (The internally used helper functions are implemented in a way that they could also be used for double authorized commands if someone needs it.) Provide enums with the return codes from the TCG Main specification. For now only a single OIAP session is supported. OIAP authorized version of the commands TPM_LoadKey2 and TPM_GetPubKey are provided. Both features are available using the 'tpm' command, too. Authorized commands are enabled with CONFIG_TPM_AUTH_SESSIONS. (Note that this also requires CONFIG_SHA1 to be enabled.)
