d0d8a935b2 Blind operations on the secret
I'm not sure this is necessary, because it is only multiplied by xm2 which is
already random and secret, but OTOH, xm2 is related to a public value, so
let's add blinding with a random value that's only use for blinding, just to
be extra sure.

- reference handshake tests that we get the right values (not much now, but

- random handshake in addition tests our generate/write functions against our
  read functions, that are tested by the reference handshake, and will be
further tested in the test suite later against invalid inputs

fdbdd72b8b Skip to trusted certs early in the chain
This helps in the case where an intermediate certificate is directly trusted.
In that case we want to ignore what comes after it in the chain, not only for
performance but also to avoid false negatives (eg an old root being no longer
trusted while the newer intermediate is directly trusted).

4d04cdcd12 Fix RSA mutex fix
Once the mutex is acquired, we must goto cleanup rather that return.
Since cleanup adjusts the return value, adjust that in test cases.

Also, at cleanup we don't want to overwrite 'ret', or we'll loose track of
errors.

0a8857435c DTLS: treat bad MAC on Finished as an error
This is not required nor recommended by the protocol, and it's a layering
violation, but it's a know flaw in the protocol that you can't detect a PSK
auth error in any other way, so it is probably the right thing to do.

fa67ebaebb Fix X.509 keysize check with multiple CAs
Assume we have two trusted CAs with the same name, the first uses ECDSA 256
bits, the second RSA 2048; cert is signed by the second. If we do the keysize
check before we checked the key types match, we'll raise the badkey flags when
checking the EC-256 CA and it will remain up even when we finally find the
correct CA. So, move the check for the key size after signature verification,
which implicitly checks the key type.

bcf13bab5d Fix issue with MemSan and entropy
Due to the recent change about entropy sources strength, it is no longer
acceptable to just disable the platform source. So, instead "fix" it so that
it is clear to MemSan that memory is initialized.

I tried __attribute__((no_sanitize_memory)) and MemSan's blacklist file, but
couldn't seem to get them to work.

- use safer tests (eg == OPTIONAL vs != REQUIRED)
