Patch 1 fixes the HMAC-SHA1 comparison in trusted_tpm1 to be constant-time. Patch 2 simplifies the SHA-1 and HMAC-SHA1 computation in trusted_tpm1 by using library APIs instead of crypto_shash. Note that this depends on the SHA-1 and HMAC-SHA1 library APIs that were merged for v6.17-rc1. Patch 3 is a trusted_tpm1 cleanup that moves private functionality out of a public header.
