HPKE functions for each KEM. (Especially if we ever need to implement
SetupPSK*, SetupAuth*, or SetupAuthPSK*.)

This replaces the ID-based API with one that is more static linker
friendly. For ECH, it doesn't make a difference because we currently
pull in all the options we've implemented. But this means other HPKE
uses need not pull in everything ECH needs and vice versa.
Along the way, fix an inconsistency: we prefixed all the AEAD constants
with "AEAD", but not the others. Since the rest of the name already
determines everything, go with the shorter version.

Although we only support X25519 right now, we may need to support other
KEMs in the future. In the general case, a public/private keypair is
less meaningful. (If something like NTRU-HRSS even goes here, I guess
it'd be the entropy passed to HRSS_encap.)
Instead of taking an entire keypair, just take the private key. Perhaps
we call it the "seed"?

PKCS#7 stores certificates and CRLs in (implicitly-tagged) SET OF
types. This means they're unordered and, in DER, must be sorted.
We currently sort neither. OpenSSL upstream sorts CRLs but doesn't sort
certificates. https://github.com/openssl/openssl/pull/13143 reports that
Microsoft has a stricter parser that checks this. This CL fixes both
fields in our serializer.
This does not change the parsing code, which still preserves whatever
order we happened to find, but I've updated the documentation to clarify
that callers should not rely on the ordering.
Based on [0] and the odd order in kPKCS7NSS, I believe this aligns with
NSS's behavior.
Update-Note: It is no longer the case that constructing a PKCS#7 file
and parsing them back out will keep the certificates and CRLs in the
same order.

These functions are not in any released version of OpenSSL. The history
is they were added to 1.0.2 beta for CT, but then removed in favor of
i2d_re_X509_tbs. We forked in between the two events.
I'm not sure what the reasoning was upstream's end. I'm thinking:
- X509 currently only captures the serialized TBSCertificate. It might
be nice to capture the whole Certificate to avoid needing a
serialization in X509_cmp and make it easier to interop with other
stacks. (Unclear.) That would require not exporting the X509_CINF
standalone for serialization.
- The modified bit means, without locking, i2d_X509 is not const or
thread-safe. We *might* be able to shift the re-encoding to
i2d_re_X509_tbs, which is already inherently non-const. That requires
not having X509_CINF_set_modified.
I'm not sure how feasible either of these are, but between that,
upstream alignment, and X509_CINF otherwise being absent from public
accessors, it seems worth removing.
Update-Note: X509_get_cert_info, X509_CINF_set_modified, and
X509_CINF_get_signature are removed. I believe all callers have been
updated. Callers should use i2d_re_X509_tbs, i2d_X509_tbs, and
X509_get0_tbs_sigalg instead.

The X509_ATTRIBUTE structure includes a hack to tolerate malformed
attributes that encode the value directly instead of a set of values.
This form is never created by OpenSSL and shouldn't be needed any more.
(Imported from upstream's e20b57270dece66ce2c68aeb5d14dd6d9f3c5d68.)
This also changes X509_ATTRIBUTE_set1_data slightly. Previously,
set1_data would override whatever was previously in the X509_ATTRIBUTE,
but leak memory. Now set1_data appends to the set. (PKCS#10 attributes
use SET OF ANY as value.) It's unclear to me if this was intentional on
upstream's part. (The attrtype == 0 case only makes sense in the old
behavior.) Since there is no other way to create a two-element SET and
upstream has long since released this behavior, I left it matching
upstream.
Update-Note: Given OpenSSL hasn't accepted these for five years, it's
unlikely anything depends on it. If something breaks, we can revert this
and revisit. No one calls X509_ATTRIBUTE_set1_data on a non-empty
X509_ATTRIBUTE, so the behavior change there should be safe.

The ASN1_BOOLEAN representation is a mess. ASN1_BOOLEAN is an int
and if non-negative (negative values mean omitted or default), gets cast
to uint8_t and encoded as the value. This means callers are simply
expected to know true is 0xff, not 1. Fix this by only encoding 0 or
0xff.
This also fixes a bug where values like 0x100 are interpreted as true
(e.g. in the tasn_enc.c logic to handle default values), but encoded as
false because the cast only looks at the least significant byte.
This CL does not change the parsing behavior, which is to allow any BER
encoding and preserve the value in the in-memory representation (though
we should tighten that). However the BER encode will no longer be
preserved when re-encoding.
Update-Note: Callers setting ASN1_BOOLEANs to a positive value other
than 0xff will now encode 0xff. This probably fixes a bug, but if anyone
was attaching significance to incorrectly-encoded booleans, that will
break.

Although it is strictly fine to call SHA512_Final in SHA384_Final
(array sizes in C parameters are purely decorational, according to the
language), GCC 11 reportedly checks now and gets upset about the size
mismatch. Use an unsized helper function so all our code matches the
specified bounds.
Unfortunately, the bounds in all the functions are a bit misleading
because SHA512_Final really outputs based on sha->md_len (which Init
function you called) rather than which Final function. I've fixed this
places within a library where we mismatched and added asserts to the
smaller functions. SHA512_Final is assert-less because I've seen lots of
code use SHA384_Init / SHA512_Update / SHA512_Final.
This doesn't fix the SHA256 variant since that is generated by a pile of
macros in a multiply-included file. This is probably a good opportunity
to make that code less macro-heavy.
Update-Note: There is a small chance the asserts will trip something,
but hopefully not since I've left SHA512_Final alone.

of attributes recognized as aliases of this extensions attribute. This
is not used by anyone and not thread-safe. Remove it and only support
the two default attribute types.
From there, document the remaining functions.
Update-Note: This removes a pair of unused functions.

This fixes a bug in ASN1_TYPE_get. Partly imported from upstream's
261ec72d58af64327214a78ca1c54b169ad93c28, though I don't believe
ASN1_TYPE_set was broken per se. There's also a lot more than in that
commit.
I've added a test to ensure we maintain the unused bits invariant
anyway, in case external code relies on it. (The invariant comes from
the pointer being NULL-initialized and from ASN1_primitive_free zeroing
*pval on free.)

This API does not come from OpenSSL, but OpenSSL does not appear to have
any way to get this information. There is X509_get0_pubkey_bitstr, but
that only works for X509 objects, not X509_PUBKEY.

In trying to figure out why ASan (which normally catches overlapping
memcpys) didn't flag this, I noticed that we actually don't have tests
for empty inputs. I've added them to cipher_tests.txt where missing and
fixed a bad assert in ofb.c.
ASan still doesn't flag this because LLVM even requires memcpy handle
dst == src. Still, fixing it is less effort than getting a clear answer
from GCC and MSVC. Though this puts us in the frustrating position of
trying to follow a C rule that our main toolchain and sanitizer disavow.

All our EVP_CIPHERs are deterministic, so there's usually no point in
testing only one direction. Some of the ECB tests were missing free
decryption tests. CTR is the same in both directions, but we ought to
test the API agrees. OFB vectors are doubled up, so we can merge them
together. Plus there are typos in the OFB-AES192.Decrypt tests, also
present upstream, so we weren't actually testing everything we should.
(I haven't removed the direction-specific logic altogether since the
tests imported from nist_cavp rely on it. Though there may be something
to be said for running them both ways since they don't actually double
them up...)

In doing so, this switches make_errors.go to take library names as
parameters rather than detecting it from the CWD. (I considered
detecting it, but then we'd need to map evp -> crypto/whatever and
crypto/whatever -> evp in both directions.)
Since crypto/hpke currently sits in the EVP namespace, I've gone ahead
and added that, so it should be easier to define new errors in
crypto/hpke. I've not added crypto/cipher, etc., yet. Moving those will
be a breaking change (consumers that put ERR_LIB_CIPHER and ERR_LIB_EVP
in a switch/case need patches).

The representation here is a bit more messy than necessary. In doing so,
clean up the variable names and smooth away two rough edges:
- X509_ALGOR_get0 would leave *out_param_value uninitialized if
*out_param_type is V_ASN1_UNDEF. Instead, set it to NULL, so callers
do not accidentally use an uninitialized pointer.
- X509_PUBKEY_set0_param, if key is NULL, would leave the key alone. No
one calls this function externally and none of the (since removed)
callers in OpenSSL rely on this behavior. A NULL check here adds a
discontinuity at the empty string that seems unnecessary here:
changing the algorithm without changing the key isn't useful.
(Note the API doesn't support changing the key without the algorithm.)
Note for reviewing: the representation of ASN1_TYPE is specified
somewhat indirectly. ASN1_TYPE uses the ASN1_ANY ASN1_ITEM, which has
utype V_ASN1_ANY. Then you look at asn1_d2i_ex_primitive and asn1_ex_c2i
which peel off the ASN1_TYPE layer and parse directly into the value
field, with a fixup for NULL. Hopefully we can rework this someday...
