This is a skin deep change, which simply renames most places where we talk
about curves in a TLS context to groups. This is because TLS1.3 has renamed
the extension, and it can now include DH groups too. We still only support
curves, but this rename should pave the way for a future extension for DH
groups.

As documented both SSL_get0_dane_authority() and SSL_get0_dane_tlsa()
are expected to return a negative match depth and nothing else when
verification fails. However, this only happened when verification
failed during chain construction. Errors in verification of the
constructed chain did not have the intended effect on these functions.
This commit updates the functions to check for verify_result ==
X509_V_OK, and no longer erases any accumulated match information
when chain construction fails. Sophisticated developers can, with
care, use SSL_set_verify_result(ssl, X509_V_OK) to "peek" at TLSA
info even when verification fail. They must of course first check
and save the real error, and restore the original error as quickly
as possible. Hiding by default seems to be the safer interface.
Introduced X509_V_ERR_DANE_NO_MATCH code to signal failure to find
matching TLSA records. Previously reported via X509_V_ERR_CERT_UNTRUSTED.
This also changes the "-brief" output from s_client to include
verification results and TLSA match information.
Mentioned session resumption in code example in SSL_CTX_dane_enable(3).
Also mentioned that depths returned are relative to the verified chain
which is now available via SSL_get0_verified_chain(3).
Added a few more test-cases to danetest, that exercise the new
code.
Resolved thread safety issue in use of static buffer in
X509_verify_cert_error_string().
Fixed long-stating issue in apps/s_cb.c which always sets verify_error
to either X509_V_OK or "chain to long", code elsewhere (e.g.
s_time.c), seems to expect the actual error. [ The new chain
construction code is expected to correctly generate "chain
too long" errors, so at some point we need to drop the
work-arounds, once SSL_set_verify_depth() is also fixed to
propagate the depth to X509_STORE_CTX reliably. ]

s_socket.c gets brutally cleaned out and now consists of only two
functions, one for client and the other for server. They both handle
AF_INET, AF_INET6 and additionally AF_UNIX where supported. The rest
is just easy adaptation.
Both s_client and s_server get the new flags -4 and -6 to force the
use of IPv4 or IPv6 only.
Also, the default host "localhost" in s_client is removed. It's not
certain that this host is set up for both IPv4 and IPv6. For example,
Debian has "ip6-localhost" as the default hostname for [::1]. The
better way is to default |host| to NULL and rely on BIO_lookup() to
return a BIO_ADDRINFO with the appropriate loopback address for IPv4
or IPv6 as indicated by the |family| parameter.

s_server was trying to set the ECDH curve when no-ec was defined. This also
highlighted the fact that the -no_ecdhe option to s_server is broken, and
doesn't make any sense any more (ECDHE is on by default and the only way it
can be disabled is through the cipherstring). Therefore this commit removes
the option.

The "-unix <path>" argument allows s_server and s_client to use a unix
domain socket in the filesystem instead of IPv4 ("-connect", "-port",
"-accept", etc). If s_server exits gracefully, such as when "-naccept"
is used and the requested number of SSL/TLS connections have occurred,
then the domain socket file is removed. On ctrl-C, it is likely that
the stale socket file will be left over, such that s_server would
normally fail to restart with the same arguments. For this reason,
s_server also supports an "-unlink" option, which will clean up any
stale socket file before starting.
If you have any reason to want encrypted IPC within an O/S instance,
this concept might come in handy. Otherwise it just demonstrates that
there is nothing about SSL/TLS that limits it to TCP/IP in any way.
(There might also be benchmarking and profiling use in this path, as
unix domain sockets are much lower overhead than connecting over local
IP addresses).
