2a0707210a Prevent Channel ID and Custom Extensions on 0-RTT.
Channel ID is incompatible with 0-RTT, so we gracefully decline 0-RTT
as a server and forbid their combination as a client. We'll keep this
logic around until Channel ID is removed.

Channel ID will be replaced by tokbind which currently uses custom
extensions. Those will need additional logic to work with 0-RTT.
This is not implemented yet so, for now, fail if both are ever
configured together at all. A later change will allow the two to
combine.

794cc59e25 Send half-RTT tickets when negotiating 0-RTT.
Once 0-RTT data is added to the current 0-RTT logic, the server will
trigger a write when processing incoming data via SSL_read. This means
SSL_read will block on transport write, which is something we've not
tried to avoid far (assuming no renegotiation).

The specification allows for tickets to be sent at half-RTT by
predicting the client Finished. By doing this we both get the tickets on
the wire sooner and avoid confusing I/O patterns. Moreover, we
anticipate we will need this mode for one of the QUIC stateless reject
patterns.

This is tested by always processing NewSessionTickets in the
ExpectHalfRTTData path on 0-RTT connections. As not other
implementations using BoGo may not do this, this is configurable via the
shim config.

02084ea398 Decouple PKCS8_encrypt and PKCS8_decrypt's core from crypto/asn1.
These will be used by Chromium's crypto::ECPrivateKey to work with
EncryptedPrivateKeyInfo structures.

Note this comes with a behavior change: PKCS8_encrypt and PKCS8_decrypt
will no longer preserve PKCS#8 PrivateKeyInfo attributes. However, those
functions are only called by Chromium which does not care. They are also
called by the PEM code, but not in a way which exposes attributes.

The PKCS#12 PFX code is made to use PKCS8_parse_encrypted_private_key
because it's cleaner (no more tossing X509_SIG around) and to ease
decoupling that in the future.

crypto/pkcs8's dependency on the legacy ASN.1 stack is now limited to
pkcs8_x509.c.

7ce10d5da7 Partially split out crypto/pkcs8's legacy ASN.1 dependencies.
PKCS8_encrypt and PKCS8_decrypt still need to be split. The code for
processing PKCS#12 files is, for now, placed entirely in pkcs8_x509.c.
If we need to split it up, it should be straightforward to do so.
(Introduce a CRYPTO_BUFFER version of PKCS12_get_key_and_certs and go
from there.)

8cd7bbf514 Push password encoding back into pkcs12_key_gen.
With PKCS8_encrypt_pbe and PKCS8_decrypt_pbe gone in
3e8b782c0c, we can restore the old
arrangement where the password encoding was handled in pkcs12_key_gen.
This simplifies the interface for the follow-up crypto/asn1 split.

Note this change is *not* a no-op for PKCS#12 files which use PBES2.
Before, we would perform the PKCS#12 password encoding for all parts of
PKCS#12 processing. The new behavior is we only perform it for the parts
that go through the PKCS#12 KDF. For such a file, it would only be the
MAC.

I believe the specification supports our new behavior. Although RFC 7292
B.1 says something which implies that the transformation is about
converting passwords to byte strings and would thus be universal,
appendix B itself is prefaced with:

   Note that this method for password privacy mode is not recommended
   and is deprecated for new usage.  The procedures and algorithms
   defined in PKCS #5 v2.1 [13] [22] should be used instead.
   Specifically, PBES2 should be used as encryption scheme, with PBKDF2
   as the key derivation function.

"This method" refers to the key derivation and not the password
formatting, but it does give support to the theory that password
formatting is tied to PKCS#12 key derivation.

(Of course, if one believes PKCS#12's assertion that their inane
encoding (NUL-terminated UTF-16!) is because PKCS#5 failed to talk about
passwords as Unicode strings, one would think that PBES2 (also in
PKCS#5) would have the same issue and thus need PKCS#12 to valiantly
save the day with an encoding...)

This matches OpenSSL's behavior and that of recent versions of NSS. See
https://bugzilla.mozilla.org/show_bug.cgi?id=1268141. I was unable to
figure out what variants, if any, macOS accepts.

They can be restored by compiling with -DBORINGSSL_ENABLE_DHE_TLS.

This is similar to 9c8c4188 for RC4 ciphers.

d851842228 Reduce crypto/pkcs8 dependency on OID table.
To remove the OID table from Chromium, we'll need to decouple a lot of
this code. In preparation for that, detach the easy cases from the OID
table. What remains is PBES, cipher, and digest OIDs which will be doing
in follow-up changes.

BUG=54

2d05568a7b Fix out-of-memory condition in conf.
conf has the ability to expand variables in config files. Repeatedly doing
this can lead to an exponential increase in the amount of memory required.
This places a limit on the length of a value that can result from an
expansion.

Credit to OSS-Fuzz for finding this problem.

(Imported from upstream's 04cf39207f94abf89b3964c7710f22f829a1a78f.)

The other half of the change was fixed earlier, but this logic was still
off. This code is kind of a mess and needs a rewrite, but import the
change to get it correct and sufficiently tested first.

(If we could take the sLen = -2 case away altogether, that would be
great...)

8c6467976c Remove BIGNUM and CBIGNUM crypto/asn1 types.
These too appear to be unused now that the core parsers use CBS. They
also were buggy as they silently ignored sign bits. This removes all
ASN1_PRIMITIVE_FUNCS definitions.  (The code to use them still exists as
we're not ready to diverge on tasn_*. Current thinking is we'll
eventually just ditch the code rather than do so.)
