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. ]

Some time ago, we had a ex_libs configuration setting that could be
divided into lflags and ex_libs. These got divided in two settings,
lflags and ex_libs, and the former was interpreted to be general
linking flags.
Unfortunately, that conclusion wasn't entirely accurate. Most of
those linking were meant to end up in a very precise position on the
linking command line, just before the spec of libraries the linking
depends on.
Back to the drawing board, we're diving things further, now having
lflags, which are linking flags that aren't depending on command line
position, plib_lflags, which are linking flags that should show up just
before the spec of libraries to depend on, and finally ex_libs, which
is the spec of extra libraries to depend on.
Also, documentation is changed in Configurations/README. This was
previously forgotten.

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.

CRIME protection: disable compression by default, even if OpenSSL is

work as before:
SSL_CONF_cmd(ctx, "Options", "Compression") enables compression.

Now that we're using templates, we should warn people not to edit the

being redirected through standard input. That way, we can display

apps/CA.pl and tools/c_rehash are built from template files. So far,
this was done by Configure, which created its own problems as it
forced everyone to reconfigure just because one of the template files
had changed.
Instead, have those files created as part of the normal build in apps/
and in tools/.
Furthermore, this prepares for a future where Configure may produce
entirely other build files than Makefile, and the latter can't be
guaranteed to be the holder of all information for other scripts.
Instead, configdata.pm (described below) becomes the center of
configuration information.
This introduces a few new things:
%config a hash table to hold all kinds of configuration data
that can be used by any other script.
configdata.pm a perl module that Configure writes. It currently
holds the hash tables %config and %target.
util/dofile.pl a script that takes a template on STDIN and outputs
the result after applying configuration data on it.
It's supposed to be called like this:
perl -I$(TOP) -Mconfigdata < template > result
or
perl -I$(TOP) -Mconfigdata templ1 templ2 ... > result
Note: util/dofile.pl requires Text::Template.
As part of this changed, remove a number of variables that are really
just copies of entries in %target, and use %target directly. The
exceptions are $target{cflags} and $target{lflags}, they do get copied
to $cflags and $lflags. The reason for this is that those variable
potentially go through a lot of changes and would rather deserve a
place in %config. That, however, is for another commit.
