TLS 1.3 forbids warning alerts, and sending these is a bad idea. Per RFC
6066:
If the server understood the ClientHello extension but
does not recognize the server name, the server SHOULD take one of two
actions: either abort the handshake by sending a fatal-level
unrecognized_name(112) alert or continue the handshake. It is NOT
RECOMMENDED to send a warning-level unrecognized_name(112) alert,
because the client's behavior in response to warning-level alerts is
unpredictable.
The motivation is to cut down on the number of places where we send
non-closing alerts. We can't remove them yet (SSL 3.0 and TLS 1.3 draft
18 need to go), but eventually this can be a simplifying assumption.
Already this means DTLS never sends warning alerts, which is good
because DTLS can't retransmit them.

This function is only called twice per ECDH or ECDSA operation, and
it only saves a few scalar multiplications and additions compared to
the alternative, so it doesn't need to be specialized.
As the TODO comment above the callers notes, the two calls can be
reduced to one. Implementing |ecp_nistz256_from_mont| in terms of
|ecp_nistz256_mul_mont| helps show that that change is safe.
This also saves a small amount of code size and improves testing and
verification efficiency.
Note that this is already how the function is implemented for targets
other than x86-64 in OpenSSL.

Mercifully, PKCS#12 does not actually make ContentInfo and SafeBag
mutually recursive. The top-level object in a PKCS#12 is a SEQUENCE of
data or encrypted data ContentInfos. Their payloads are a SEQUENCE of
SafeBags (aka SafeContents).
SafeBag is a similar structure to ContentInfo but not identical (it has
attributes in it which we ignore) and actually carries the objects.
There is only recursion if the SafeContents bag type is used, which we
do not process.
This means we don't need to manage recursion depth. This also no longer
allows trailing data after the SEQUENCE and removes the comment about
NSS. The test file still passes, so I'm guessing something else was
going on?

BN_FLG_CONSTTIME is a ridiculous API and easy to mess up
(CVE-2016-2178). Instead, code that needs a particular algorithm which
preserves secrecy of some arguemnt should call into that algorithm
directly.
This is never set outside the library and is finally unused within the
library! Credit for all this goes almost entirely to Brian Smith. I just
took care of the last bits.
Note there was one BN_FLG_CONSTTIME check that was still reachable, the
BN_mod_inverse in RSA key generation. However, it used the same code in
both cases for even moduli and φ(n) is even if n is not a power of two.
Traditionally, RSA keys are not powers of two, even though it would make
the modular reductions a lot easier.
When reviewing, check that I didn't remove a BN_FLG_CONSTTIME that led
to a BN_mod_exp(_mont) or BN_mod_inverse call (with the exception of the
RSA one mentioned above). They should all go to functions for the
algorithms themselves like BN_mod_exp_mont_consttime.
This CL shows the checks are a no-op for all our tests:

Avoid the X509_ALGOR dependency entirely. The public API is still using
the legacy ASN.1 structures for now, but the conversions are lifted to
the API boundary. Once we resolve that and the OID table dependency,
this module will no longer block unshipping crypto/asn1 and friends from
Chromium.
This changes the calling convention around the two kinds of PBE suites
we support. Each PBE suite provides a free-form encrypt_init function to
setup an EVP_CIPHER_CTX and write the AlgorithmIdentifer to a CBB. It
then provides a common decrypt_init function which sets up an
EVP_CIPHER_CTX given a CBS of the parameter. The common encrypt code
determines how to call which encrypt_init function. The common decrypt
code parses the OID out of the AlgorithmIdentifer and then dispatches to
decrypt_init.
Note this means the encryption codepath no longer involves parsing back
out a AlgorithmIdentifier it just serialized. We don't have a good story
to access an already serialized piece of a CBB in progress (reallocs can
invalidate the pointer in a CBS), so it's easier to cut this step out
entirely.
Also note this renames the "PBES1" schemes from PKCS#5 to PKCS#12. This
makes it easier to get at the PKCS#12 key derivation hooks. Although
PKCS#12 claims these are variants of PKCS#5's PBES1, they're not very
related. PKCS#12 swaps out the key derivation and even defines its own
AlgorithmIdentifier parameter structure (identical to the PKCS#5 PBES1
one). The only thing of PBES1 that survives is the CBC mode padding
scheme, which is deep in EVP_CIPHER for us. (Of course, all this musing
on layering is moot because we don't implement non-PKCS#12 PBES1 schemes
anyway.)
This also moves some of the random API features (default iteration
count, default salt generation) out of the PBE suites and into the
common code.

This is a remnant of signature EVP_MDs. Detach them from
EVP_get_digestby{nid,obj}. Nothing appears to rely on this for those two
functions. Alas, Node.js appears to rely on it for EVP_get_digestbyname,
so keep that working.
This avoids causing every consumer's parsing to be unintentionally lax.
It also means fewer OIDs to transcribe when detaching the last of
libcrypto from the legacy ASN.1 stack and its giant OID table.
Note this is an externally visible change. There was one consumer I had
to fix, but otherwise everything handled things incorrectly due to this
quirk, so it seemed better to just fix the API rather than fork off a
second set.

Passing in an array of scalars was removed some time ago, but a few
remnants of it remain.
