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.
Changed in v2:
- Added the requested note to the commit message of patch 1.
- Added a Reviewed-by tag

KEYS: trusted_tpm1: Compare HMAC values in constant time
KEYS: trusted_tpm1: Use SHA-1 library instead of crypto_shash
