Some HPKE consumers call into the KDF directly. We don't have an EVP_KDF
abstraction and it's not clear to me how settled "KDF" is as an
interface. (HPKE specifically assumes an extract/expand pair.)
For now, just add EVP_HPKE_KDF_hkdf_md which is defined to only work for
HKDF KDFs. As we don't implement ID -> KDF lookup ourselves and expect
callers to decide which algorithms they want to export, any future
non-HKDF-based KDF won't affect existing callers anyway. If that
happens, we can make this return an EVP_KDF or just add
EVP_HPKE_KDF_{extract,expand} depending on universal this turns out to
be.

O_CLOEXEC avoids a race condition and is less code. It was supported in
Linux starting 2.6.23. https://bugs.python.org/issue26343#msg260151 says
it's been available since macOS 10.7. Let's try using it instead of
fcntl and see if anything breaks. It's even part of POSIX these days.
Update-Note: BoringSSL's /dev/urandom code now assumes the platform
supports O_CLOEXEC.

OHTTP concatenates enc to the ciphertext without any length prefix
(unlike ECH), so an implementation would want to know the length of enc
for the chosen KEM. Add an accessor to help with that.
While I'm here, fix a couple places where we assumed a specific KEM in
the HPKE implementation (although we still only support the one KEM so
this is all moot).
There's probably something to be said for lifting the length checks out
of the KEM-specific code and into the wrappers, as we're assuming
fixed-width fields anyway. But I've left it alone for now.

Matching Chromium, Go, and TLS 1.3, only allow SHA-256, SHA-384, and
SHA-512 RSA-PSS signatures, where MGF-1 and message hash match and salt
length is hash length. Sadly, we are stuck tolerating an explicit
trailerField for now. See the certificates in cl/362617931.
This also fixes an overflow bug in handling the salt length. On
platforms with 64-bit long and 32-bit int, we would misinterpret, e.g,
2^62 + 32 as 32. Also clean up the error-handling of maskHash. It was
previously handled in a very confusing way; syntax errors in maskHash
would succeed and only be noticed later, in rsa_mgf1_decode.
I haven't done it in this change, but as a followup, we can, like
Chromium, reduce X.509 signature algorithms down to a single enum.
Update-Note: Unusual RSA-PSS combinations in X.509 are no longer
accepted. This same change (actually a slightly stricter version) has
already landed in Chrome.

OpenSSL renamed X509_STORE_CTX_trusted_stack to
X509_STORE_CTX_set0_trusted_stack. This name is a partially an
improvement as this is a setter, and partially a setback. The "set0"
name is a bit misleading.
set0 is narrowly correct, in that this function does not adjust
refcounts. But usually set0 functions don't adjust refcounts because
they take ownership of the input. This function does not. It simply
borrows the pointer and assumes it will remain valid for the duration of
X509_STORE_CTX.
OpenSSL also renamed X509_STORE_CTX_set_chain to
X509_STORE_CTX_set0_untrusted. I've declined to add that one for now, in
hopes that we can remove both functions. From what I can tell, there's
no point in ever using either function. It's redundant with the last
parameter to X509_STORE_CTX_init.

We only care about dates within years 0000 to 9999 for
RFC5280. timegm() is only semi-standard. Some things require the
setting awkward defines to get libc to give it to you. Other things
let you have it but make it stop working at year 3000. Still other
things have 32 bit time_t.....
Let's just make our own that actually works. all the time, does
everything with an int64_t, and fails if you want to send something
out that would overflow a 32 bit time_t.
In the process of doing this, we get rid of the old Julian date stuff
from OpenSSL, which while functional was a bit awkward dealing only
with days, and using the Julian calendar as the reference point instead of potentially something more useful. Julian seconds since Jan 1 1970
00:00:00 UCT are much more useful to us than Julian days since a
Julian epoch.
The OS implementations of timegm() and gmtime() also can be pretty
complex, due to the nature of needing multiple timezone, daylight
saving, day of week, and other stuff we simply do not need for
doing things with certificate times. A small microbenchmark of
10000000 of each operation comparing this implementation to
the system version on my M1 mac gives:

resolves a TODO that ASN1_STRING_print_ex was inconsistently checking
for invalid codepoints. It also removes an optimization when

invalid.
Finally, this removes UTF8_getc, which no longer has any callers.

No sense in keeping two around. This does cause the functions to reject
some previously accepted invalid inputs. These were intentionally
accepted by
https://boringssl-review.googlesource.com/c/boringssl/+/13082 for
an old version of M2Crypto, but I belive we no longer need to be
compatible with that.
Update-Note: ASN1_TIME_print, ASN1_UTCTIME_print, and
ASN1_GENERALIZEDTIME_print will no longer accept various invalid inputs.

This may be okay because of the strict aliasing character type rule, but
easier not to think about it.
