Start converting the ones we can right now. Some of the messier ones
resize init_buf rather than assume the initial size is sufficient, so
those will probably wait until init_buf is gone and the handshake's
undergone some more invasive surgery. The async ones will also require
some thought. But some can be incrementally converted now.

Deprecate the client_cert_cb variant since you can't really configure

Putting it at the top was probably a mistake? Even though SSL_CIPHER
(like SSL_SESSION) doesn't depend on SSL, if you're reading through the
header, SSL_CTX and SSL are the most important types. You could even use
the library without touch cipher suite configs if you don't care since
the default is decently reasonable, though it does include a lot of
ciphers. (Hard to change that if we wanted to because DEFAULT is often
used somewhat like ALL and then people subtract from it.)

The cipher suite rules could also be anchored on SSL_TXT_* if desired. I
currently documented them in prose largely because SSL_TXT_* also
defines protocol version strings and those are weird; SSL_TXT_TLSV1_1
isn't even a cipher rule. (And, in fact, those are the only SSL_TXT_*
macros that we can't blindly remove. I found some code that #ifdef's the
version SSL_TXT_* macros to decide if version-locked SSL_METHODs are
available.)
Also they clutter the header. I was thinking maybe we should dump a lot
of the random constants into a separate undocumented header or perhaps
just unexport them.
I'm slightly torn on this though and could easily be convinced in the
other direction. (Playing devil's advocate, anchoring on SSL_TXT_* means
we're less likely to forget to document one so long as adding a
SSL_TXT_* macro is the convention.)

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.
