Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around
our FOO_up_ref functions and opaque libssl types. This causes some
difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER
checks for 1.1.0 APIs we have will be wrong.
Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can
break external projects. It is common to implement a compatibility
version of an accessor under #ifdef as a static function. This then
conflicts with our headers if we, unlike OpenSSL 1.0.2, have this
function.
This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds
enough accessors for software with 1.1.0 support already. The hope is
this will unblock hiding SSL_CTX and SSL_SESSION, which will be
especially useful with C++-ficiation. The cost is we will hit some
growing pains as more 1.1.0 consumers enter the ecosystem and we
converge on the right set of APIs to import from upstream.
It does not remove any 1.0.2 APIs, so we will not require that all
projects support 1.1.0. The exception is APIs which changed in 1.1.0 but
did not change the function signature. Those are breaking changes.
Specifically:
- SSL_CTX_sess_set_get_cb is now const-correct.
- X509_get0_signature is now const-correct.
For C++ consumers only, this change temporarily includes an overload
hack for SSL_CTX_sess_set_get_cb that keeps the old callback working.
This is a workaround for Node not yet supporting OpenSSL 1.1.0.
The version number is set at (the as yet unreleased) 1.1.0g to denote
that this change includes https://github.com/openssl/openssl/pull/4384.

The only place it is used is EC_KEY_{dup,copy} and no one calls that
function on an EC_KEY with ex_data. This aligns with functions like
RSAPublicKey_dup which do not copy ex_data. The logic is also somewhat
subtle in the face of malloc errors (upstream's PR 3323).
In fact, we'd even changed the function pointer signature from upstream,
so BoringSSL-only code is needed to pass this pointer in anyway. (I
haven't switched it to CRYPTO_EX_unused because there are some callers
which pass in an implementation anyway.)
Note, in upstream, the dup hook is also used for SSL_SESSIONs when those
are duplicated (for TLS 1.2 ticket renewal or TLS 1.3 resumption). Our
interpretation is that callers should treat those SSL_SESSIONs
equivalently to newly-established ones. This avoids every consumer
providing a dup hook and simplifies the interface.
(I've gone ahead and removed the TODO(fork). I don't think we'll be able
to change this API. Maybe introduce a new one, but it may not be worth
it? Then again, this API is atrocious... I've never seen anyone use argl
and argp even.)

It seems risky in the context of cross-signed certificates when the
same certificate might have multiple potential issuers. Also rarely
used, since chains in OpenSSL typically only employ self-signed
trust-anchors, whose self-signatures are not checked, while untrusted
certificates are generally ephemeral.
(Imported from upstream's 0e76014e584ba78ef1d6ecb4572391ef61c4fb51.)
This is in master and not 1.0.2, but having a per-certificate signature
cache when this is a function of signature and issuer seems dubious at
best. Thanks to Viktor Dukhovni for pointing this change out to me.
(And for making the original change upstream, of course.)

The logic to reset *pp doesn't actually work if pp is NULL. (It also doesn't
work if *pp is NULL, but that didn't work before either.) Don't bother
resetting it. This is consistent with the template-based i2d functions which do
not appear to leave *pp alone on error.

OpenSSL upstream did a bulk reformat. We still have some files that have
the old OpenSSL style and this makes applying patches to them more
manual, and thus more error-prone, than it should be.
This change is the result of running
util/openssl-format-source -v -c .
in the enumerated directories. A few files were in BoringSSL style and
have not been touched.
This change should be formatting only; no semantic difference.

This callback is never used. The one caller I've ever seen is in Android
code which isn't built with BoringSSL and it was a no-op.
It also doesn't actually make much sense. A callback cannot reasonably
assume that it sees every, say, SSL_CTX created because the index may be
registered after the first SSL_CTX is created. Nor is there any point in
an EX_DATA consumer in one file knowing about an SSL_CTX created in
completely unrelated code.
Replace all the pointers with a typedef to int*. This will ensure code
which passes NULL or 0 continues to compile while breaking code which
passes an actual function.
This simplifies some object creation functions which now needn't worry
about CRYPTO_new_ex_data failing. (Also avoids bouncing on the lock, but
it's taking a read lock, so this doesn't really matter.)

Actually this one was reported by us, but the commit message doesn't
mention this.
This is slightly modified from upstream's version to fix some problems
noticed in import. Specifically one of d2i_X509_AUX's success paths is
bust and d2i_PrivateKey still updates on one error path. Resolve the
latter by changing both it and d2i_AutoPrivateKey to explicitly hit the
error path on ret == NULL. This lets us remove the NULL check in
d2i_AutoPrivateKey.
We'll want to report the problems back upstream.

Instead, each module defines a static CRYPTO_EX_DATA_CLASS to hold the values.
This makes CRYPTO_cleanup_all_ex_data a no-op as spreading the
CRYPTO_EX_DATA_CLASSes across modules (and across crypto and ssl) makes cleanup
slightly trickier. We can make it do something if needbe, but it's probably not
