OpenSSL's EVP-level EC API involves a separate "paramgen" operation,
which is ultimately just a roundabout way to go from a NID to an
EC_GROUP. But Node uses this, and it's the pattern used within OpenSSL
these days, so this appears to be the official upstream recommendation.
Also add a #define for OPENSSL_EC_EXPLICIT_CURVE, because Node uses it,
but fail attempts to use it. Explicit curve encodings are forbidden by
RFC 5480 and generally a bad idea. (Parsing such keys back into OpenSSL
will cause it to lose the optimized path.)

Prior to 82639e6f we used thread-local data for the PRNG state. That
change switched to using a mutex-protected pool instead in order to save
memory in heavily-threaded applications.
However, the pool mutex can get extremely hot in cases where the PRNG is
heavily used. 8e8f2504 was a short-term work around, but supporting both
modes is overly complex.
This change moves back to the state of the prior to 82639e6f. The best
way to review this is to diff the changed files against '82639e6f^' and
note that the only difference is a comment added in rand.c:

We switched from thread-local storage to a mutex-pool in 82639e6f53
because, for highly-threaded processes, the memory used by all the

fine, but had underestimated the PRNG requirements of some of our jobs.
This change makes rand.c support using either thread-locals or a
mutex-pool. Thread-locals are used if fork-unsafe buffering is enabled.
While not strictly related to fork-safety, we already have the
fork-unsafe control, and it's already set by jobs that care a lot about
PRNG performance, so fits quite nicely here.

If BIO_read returns partial reads, d2i_*_bio currently fails. This is a
partial (hah) regression from 419144adce.
The old a_d2i_fp.c code did *not* tolerate partial reads in the ASN.1
header, but it *did* tolerate them in the ASN.1 body. Since partial
reads are more likely to land in the body than the header, I think we
can say d2i_*_bio was "supposed to" tolerate this but had a bug in the
first few bytes.
Fix it for both cases. Add a regression test for this and the partial
write case (which works fine).

JDK 11 shipped with a TLS 1.3 implementation enabled by default.
Unfortunately, that implementation does not work and fails to send the
SNI extension on resumption. See
https://bugs.openjdk.java.net/browse/JDK-8211806.
This means servers which enable TLS 1.3 will see JDK 11 clients work on
the first connection and then fail on all subsequent connections. Add
SSL_set_jdk11_workaround which configures a workaround to fingerprint
JDK 11 and disable TLS 1.3 with the faulty clients.
JDK 11 also implemented the downgrade signal, which means that
connections that trigger the workaround also must not send the downgrade
signal. Unfortunately, the downgrade signal's security properties are
sensitive to the existence of any unmarked TLS 1.2 ServerHello paths. To
salvage this, pick a new random downgrade marker for this scenario and
modify the client to treat it as an alias of the standard one.
Per the link above, JDK 11.0.2 will fix this bug. Hopefully the
workaround can be retired sometime after it is released.

C99 added macros such as PRIu64 to inttypes.h, but it said to exclude them from
C++ unless __STDC_FORMAT_MACROS or __STDC_CONSTANT_MACROS was defined. This
text was never incorporated into any C++ standard and explicitly overruled in
C++11.
Some libc headers followed C99. Notably, glibc prior to 2.18
(https://sourceware.org/bugzilla/show_bug.cgi?id=15366) and old versions of the
Android NDK.
In the NDK, although it was fixed some time ago (API level 20), the NDK used to
use separate headers per API level. Only applications using minSdkVersion >= 20
would get the fix. Starting NDK r14, "unified" headers are available which,
among other things, make the fix available (opt-in) independent of
minSdkVersion. In r15, unified headers are opt-out, and in r16 they are
mandatory.
Try removing these and see if anyone notices. The former is past our five year
watermark. The latter is not and Android has hit
https://boringssl-review.googlesource.com/c/boringssl/+/32686 before, but
unless it is really widespread, it's probably simpler to ask consumers to
define __STDC_CONSTANT_MACROS and __STDC_FORMAT_MACROS globally.
Update-Note: If you see compile failures relating to PRIu64, UINT64_MAX, and
friends, update your glibc or NDK. As a short-term fix, add
__STDC_CONSTANT_MACROS and __STDC_FORMAT_MACROS to your build, but get in touch
so we have a sense of how widespread it is.

Ryan noticed that CBS_ASN1_{SEQUENCE,SET} used CBS_ASN1_CONSTRUCTED
before it was defined. The C preprocessor expands late, so this works,
but it is weird. Flip the order.
There was also some question about the constructed bit, which is
different from how ASN.1 formally specifies it. (ASN.1 believes the
constructed bit is a property of the element, not the tag. We fold it in
because it's entirely computable[*] from the type in DER, so it's easier
to fold it in.) Move existing text to the section header and expand on
it.
[*] DER forbids constructed strings so string types are always
primitive. ASN.1 forbids implicitly tagging CHOICE or ANY, so the
inherited constructed bit cannot vary by value.
