Use the SHA-1 and HMAC-SHA1 library functions instead of crypto_shash. This is simpler and faster. Replace the selection of CRYPTO, CRYPTO_HMAC, and CRYPTO_SHA1 with CRYPTO_LIB_SHA1 and CRYPTO_LIB_UTILS. The latter is needed for crypto_memneq() which was previously being pulled in via CRYPTO.

Enable use of the Trusted Platform Module (TPM) as trusted key

backend. Trusted keys are random number symmetric keys,

which will be generated and RSA-sealed by the TPM.

The TPM only unseals the keys, if the boot PCRs and other

criteria match.
