- Remove warning about unable to find FAPI when it's is not-compiled
in and not chosen as the beckend.
- Fix memory leaks in `tpm_create_transient_primary_from_template`.
- Fix `NULL` pointer dereference in `db.c` on uses of `CKA_ALLOWED_MECHANISMS`.
- Fix offset miscalculation in FAPI backend that was corrupting data.
- Support `CKM_ECDH1_DERIVE` via `C_DeriveKey`.

bump as its internal to builders only. However `--enable-fapi` left in
place for backwards compat.
