Although the previous commit should ensure this doesn't happen, the
uint8_t** pattern is very error-prone and we're trying to avoid doing
much to the legacy ASN.1 stack. To that end, maintaining the strong
exception guarantee w.r.t. the input pointer-pointer is best effort and
we won't rely on it, so we needn't spend our time chasing down problems.

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.

The IUF functions were added for PEM and internally are very lenient to
whitespace and include other PEM-specific behaviors (notably they treat
hyphens as EOF). They also decode a ton of invalid input (see upstream's
RT #3757).
Upstream has a rewrite with tests that resolves the latter issue which
we should review and import. But this is still a very PEM-specific
interface. As this code has basically no callers outside the PEM code
(and any such callers likely don't want a PEM-specific API), it's
probably not worth the trouble to massage this and PEM into a strict IUF
base64 API with PEM whitespace and hyphen bits outside. Just deprecate
it all and leave it in a corner.

Allow configuring digest preferences for the private key. Some
smartcards have limited support for signing digests, notably Windows
CAPI keys and old Estonian smartcards. Chromium used the supports_digest
hook in SSL_PRIVATE_KEY_METHOD to limit such keys to SHA1. However,
detecting those keys was a heuristic, so some SHA256-capable keys
authenticating to SHA256-only servers regressed in the switch to
BoringSSL. Replace this mechanism with an API to configure digest
preference order. This way heuristically-detected SHA1-only keys may be
configured by Chromium as SHA1-preferring rather than SHA1-requiring.
In doing so, clean up the shared_sigalgs machinery somewhat.

Estonian IDs issued between September 2014 to September 2015 are broken and use
negative moduli. They last five years and are common enough that we need to
work around this bug.
Add parallel "buggy" versions of BN_cbs2unsigned and RSA_parse_public_key which
tolerate this mistake, to align with OpenSSL's previous behavior. This code is
currently hooked up to rsa_pub_decode in RSA_ASN1_METHOD so that d2i_X509 is
tolerant. (This isn't a huge deal as the rest of that stack still uses the
legacy ASN.1 code which is overly lenient in many other ways.)
In future, when Chromium isn't using crypto/x509 and has more unified
certificate handling code, we can put client certificates under a slightly
different codepath, so this needn't hold for all certificates forever. Then in
September 2019, when the broken Estonian certificates all expire, we can purge
this codepath altogether.

Unfortunately, these are also some of the worst APIs in the SSL stack.
I've tried to capture all the things they expose to the caller. 0 vs -1
is intentionally left unexpanded on for now. Upstream's documentation
says 0 means transport EOF, which is a nice idea but isn't true. (A lot
of random functions return 0 on error and pass it up to the caller.)
https://crbug.com/466303 tracks fixing that.
SSL_set_bio is intentionally documented to NOT be usable when they're
already configured. The function tries to behave in this case and even
with additional cases when |rbio| and/or |wbio| are unchanged, but this
is buggy. For instance, this will explode:
SSL_set_bio(ssl, bio1, bio1);
SSL_set_bio(ssl, bio2, SSL_get_wbio(ssl));
As will this, though it's less clear this is part of the API contract
due to SSL taking ownership.
SSL_set_bio(ssl, bio1, bio2);
SSL_set_bio(ssl, bio2, bio1);
It also tries to handle ssl->bbio already existing, but I doubt it quite
works. Hopefully we can drop ssl->bbio eventually. (Why is this so
complicated...)
