--prefix is now exclusively used for software and manual installation.
--openssldir is not exclusively used as a default location for certs,
keys and the default openssl.cnf.

This change is made to bring clarity, to have the two less
intertwined, and to be more compatible with the usual ways of software
installation.

Please change your habits and scripts to use --prefix rather than
--openssldir for installation location now.

It's time to refactor the handling of %disabled so that all
information of value is in the same place.  We have so far had a few
cascading disable rules in form of code, far away from %disabled.
Instead, bring that information to the array @disable_cascade, which
is a list of pairs of the form 'test => descendents'.  The test part
can be a string, and it's simply checked if that string is a key in
%disabled, or it can be a CODEref to do a more complex test.  If the
test comes true, then all descendents are disabled.  This check is
performed until there are no more things that need to be disabled.

Also, $default_depflags is constructed from the information in
%disabled instead of being a separate string.  While a string of its
own is visually appealing, it's much too easy to forget to update it
when something is changed in %disabled.

The way the "reconf"/"reconfigure" argument is handled is overly
complicated.  Just grep for it first, and if it is there in the
current arguments, get the old command line arguments from Makefile.

While we're at it, make the Makefile variable CONFIGURE_ARGS hold the
value as a perl list of strings.  This makes things much safer in case
one of the arguments would contain a space.  Since CONFIGURE_ARGS is
used for nothing else, there's no harm in this.

It is sometimes useful (especially in automated tests) to supply
multiple trusted or untrusted certificates via separate files rather
than have to prepare a single file containing them all.

To that end, change verify(1) to accept these options zero or more
times.  Also automatically set -no-CAfile and -no-CApath when
-trusted is specified.

Improve verify(1) documentation, which could still use some work.

Still need tests for trusted-first and tests that probe construction
of alternate chains.

Reviewed-by: Richard Levitte <levitte@openssl.org>

Returning untrusted is enough for for full chains that end in
self-signed roots, because when explicit trust is specified it
suppresses the default blanket trust of self-signed objects.

But for partial chains, this is not enough, because absent a similar
trust-self-signed policy, non matching EKUs are indistinguishable
from lack of EKU constraints.

Therefore, failure to match any trusted purpose must trigger an
explicit reject.

These can be re-generated via:

When DANE-EE(3) matches or either of DANE-EE/PKIX-EE fails, we don't
build a chain at all, but rather succeed or fail with just the leaf
certificate.  In either case also check for Suite-B violations.

As unlikely as it may seem that anyone would enable both DANE and
Suite-B, we should do what the application asks.

Split the read_config function into read_config that ONLY reads the
configuration files but doesn't try to resolve any of the
inheritances, and resolve_config which resolves the inheritance chain
of a given target.  Move them to the bottom of Configure, with the
rest of the helpers.

Have a new small hash table, %target, which will hold the values for
the target the user requested.  This also means that all access to the
current target data can be reduced from '$table{$target}->{key}' to a
mere '$target{key}'.

While we're at it, the old string formatted configurations are getting
obsolete, so they may as well get deprecated entirely.

Calling SSL_shutdown while in init previously gave a "1" response, meaning
everything was successfully closed down (even though it wasn't). Better is
to send our close_notify, but fail when trying to receive one.

The problem with doing a shutdown while in the middle of a handshake is
that once our close_notify is sent we shouldn't really do anything else
(including process handshake/CCS messages) until we've received a
close_notify back from the peer. However the peer might send a CCS before
acting on our close_notify - so we won't be able to read it because we're
not acting on CCS messages!

It seems risky in the context of cross-signed certificates when the
