SSL_TXT_FOO expands to "FOO", but SSL_TXT_AES_GCM expand "AESGCM" and

This is redundant with SSL_get_error. Neither is very good API, but
SSL_get_error is more common. SSL_get_error also takes a return code

immediately after an operation. (Any other point is confusing since you
can have SSL_read and SSL_write operations going on in parallel and
they'll get mixed up.)

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.)

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.
