Later CLs will clean up the ClientHello construction a bit (draft-12
avoids computing ClientHelloOuter twice). I suspect the transcript
handling on the client can also be simpler, but I'll see what's
convenient after I've changed how ClientHelloOuter is constructed.
Changes of note between draft-10 and draft-13:
- There is now an ECH confirmation signal in both HRR and SH. We don't
actually make much use of this in our client right now, but it
resolves a bunch of weird issues around HRR, including edge cases if
HRR applies to one ClientHello but not the other.
- The confirmation signal no longer depends on key_share and PSK, so we
don't have to work around a weird ordering issue.
- ech_is_inner is now folded into the main encrypted_client_hello code
point. This works better with some stuff around HRR.
- Padding is moved from the padding extension, computed with
ClientHelloInner, to something we fill in afterwards. This makes it
easier to pad up the whole thing to a multiple of 32. I've accordingly
updated to the latest recommended padding construction, and updated
the GREASE logic to match.
- ech_outer_extensions is much easier to process because the order is
required to be consistent. We were doing that anyway, and now a simple
linear scan works.
- ClientHelloOuterAAD now uses an all zero placeholder payload of the
same length. This lets us simplify the server code, but, for now, I've
kept the client code the same. I'll follow this up with a CL to avoid
computing ClientHelloOuter twice.
- ClientHelloOuterAAD is allowed to contain a placeholder PSK. I haven't
filled that in and will do it in a follow-up CL.

V_ASN1_APP_CHOOSE has been discouraged by OpenSSL since 2000:
https://git.openssl.org/gitweb/?p=openssl.git;a=blob;f=CHANGES;h=824f421b8d331ba2a2009dbda333a57493bedb1e;hb=fb047ebc87b18bdc4cf9ddee9ee1f5ed93e56aff#l10848
Instead, upstream recommends an MBSTRING_* constant.
https://www.openssl.org/docs/man1.1.1/man3/X509_NAME_add_entry_by_NID.html
This function is a bit overloaded:
MBSTRING_* means "Decode my input from this format and then re-encode it
using whatever string type best suits the NID (usually UTF8String, but
some NIDs require PrintableString)".
V_ASN1_APP_CHOOSE means "This is a Latin-1 string. Without looking at
the NID, pick one of PrintableString, IA5String, or T61String".
The latter is almost certainly not what callers want. If they want a
particular type, they can always force it by passing a particular
V_ASN1_* constant. This removes the only use of ASN1_PRINTABLE_type
within the library, though there is one external use still.
Update-Note: V_ASN1_APP_CHOOSE is removed. I only found one use, which
has been fixed.

Unlike subspan(), they also do not have clipping behavior, so we're
guaranteed the length is correct. The clipping behavior comes from

ASN1_STRING_set_by_NID is very complex and depends on a "global mask"
for most NIDs. (Some NIDs use a single type and use STABLE_NO_MASK to
disable the global mask.) Historically, it defaulted to allowing all
types, but it switched to UTF8String in OpenSSL 1.0.2.
Updating the global mask is not thread-safe, and it's 2021. Let's just
always use UTF-8. The only callers I found set it to UTF-8 anyway (with
the exception of some test script we don't use, and some code that
wasn't compiled). No-op writes in the C/C++ memory model are still race
conditions, so this CL fixes some bugs in those callers.
Update-Note: The global mask for ASN1_STRING_set_by_NID is now always
UTF-8. Callers that want another type should reconsider and, if UTF-8 is
still unsuitable, just pass the actual desired type into
ASN1_mbstring_copy, X509_NAME_ENTRY_set_data, etc

This flag is set when an ASN1_STRING is created from a codepath that is
aware it is an "mstring" (CHOICE of multiple string or string-like
types). With setters like X509_set_notBefore, it is very easy to
accidentally lose the flag on some field that normally has it.
The only place the flag is checked is X509_time_adj_ex. X509_time_adj_ex
usually transparently picks UTCTime vs GeneralizedTime, as in the X.509
CHOICE type. But if writing to an existing object AND if the object
lacks the flag, it will lock to whichever type the object was
previously. It is likely any caller hitting this codepath is doing so
unintentionally and has a latent bug that won't trip until 2050.
In fact, one of the ways callers might accidentally lose the
ASN1_STRING_FLAG_MSTRING flag is by using X509_time_adj_ex!
X509_time_adj_ex(NULL) does not use an mstring-aware constructor. This
CL avoids needing such a notion in the first place.
Looking through callers, the one place that wants the old behavior is a
call site within OpenSSL, to set the producedAt field in OCSP. That
field is a GeneralizedTime, rather than a UTCTime/GeneralizedTime
CHOICE. We dropped that code, but I'm making a note of it to remember
when filing upstream.
Update-Note: ASN1_STRING_FLAG_MSTRING is no longer defined and
X509_time_adj_ex now behaves more predictably. Callers that actually
wanted to lock to a specific type should call ASN1_UTCTIME_adj or
ASN1_GENERALIZEDTIME_adj instead.

If a client offers ECH, but the server rejects it, the client completes
the handshake with ClientHelloOuter in order to authenticate retry keys.
Implement this flow. This is largely allowing the existing handshake to
proceed, but with some changes:
- Certificate verification uses the other name. This CL routes this up to
the built-in verifier and adds SSL_get0_ech_name_override for the
callback.
- We need to disable False Start to pick up server Finished in TLS 1.2.
- Client certificates, notably in TLS 1.3 where they're encrypted,
should only be revealed to the true server. Fortunately, not sending
client certs is always an option, so do that.
Channel ID has a similar issue. I've just omitted the extension in
ClientHelloOuter because it's deprecated and is unlikely to be used
with ECH at this point. ALPS may be worth some pondering but, the way
it's currently used, is not sensitive.
(Possibly we should change the draft to terminate the handshake before
even sending that flight...)
- The session is never offered in ClientHelloOuter, but our internal
book-keeping doesn't quite notice.
I had to replace ech_accept with a tri-state ech_status to correctly
handle an edge case in SSL_get0_ech_name_override: when ECH + 0-RTT +
reverify_on_resume are all enabled, the first certificate verification
is for the 0-RTT session and should be against the true name, yet we
have selected_ech_config && !ech_accept. A tri-state tracks when ECH is
actually rejected. I've maintained this on the server as well, though
the server never actually cares.

OpenSSL's BIT STRING representation has two modes, one where it
implicitly trims trailing zeros and the other where the number of unused
bits is explicitly set. This means logic in ASN1_item_verify, or
elsewhere in callers, that checks flags and ASN1_STRING_length is
inconsistent with i2c_ASN1_BIT_STRING.
Add ASN1_BIT_STRING_num_bytes for code that needs to deal with X.509
using BIT STRING for some fields instead of OCTET STRING. Switch
ASN1_item_verify to it. Some external code does this too, so export it
as public API.
This is mostly a theoretical issue. All parsed BIT STRINGS use explicit
byte strings, and there are no APIs (apart from not-yet-opaquified
structs) to specify the ASN1_STRING in X509, etc., structures. We
intentionally made X509_set1_signature_value, etc., internally construct
the ASN1_STRING. Still having an API is more consistent and helps nudge
callers towards rejecting excess bits when they want bytes.
It may also be worth a public API for consistently accessing the bit
count. I've left it alone for now because I've not seen callers that
need it, and it saves worrying about bytes-to-bits overflows.
This also fixes a bug in the original version of the truncating logic
when the entire string was all zeros, and const-corrects a few
parameters.

The one place where LHASH_OF(T) appears in public APIs is
X509V3_EXT_conf_nid. This is only ever called with conf = NULL, but
cryptography.io needs to utter the type name as part of bindings. Thus
this CL keeps DECLARE_LHASH_OF and LHASH_OF macros public and the others
private.
Update-Note: BoringSSL no longer provides a general-purpose hash table
to callers. Use the language's standard library, or another
implementation.

This is a bit short of a name to take, and no one seems to be using
it. (OpenSSL has renamed it, but not unexported it.)
