It's time for print_table_entry to get a bit of refreshment.  The way it
was put together, we needed to maintain the list of known configuration
keys of interest twice, in different shapes.  This is error prone, so
move the list of strings to a common list for all printing cases, and
use simple formatting of lines to do the actual printout based on that
list.

Time to get rid of @MK1MF_Builds and introduce a more flexible
'build_scheme' configuration key.  Its value may be a string or an
array of strings, meaning we need to teach resolve_config how to
handle ARRAY referenses.

The build scheme is a word that selects a function to create the
appropriate result files for a certain configuration.  Currently valid
build schemes aer "mk1mf" and "unixmake", the plan is however to add
at least one other for a more universal build scheme.

Incidently, this also adds the functions 'add' and 'add_before', which
can be used in a configuration, so instead of having to repeatedly
write a sub like this:

	key1 => sub { join(" ", @_, "myvalues"); },
	key2 => sub { join(" ", "myvalues", @_); },

one could write this:

	key1 => add(" ", "myvalues"),
	key2 => add_before(" ", "myvalues"),

The good point with 'add' and 'add_before' is that they handle
inheritances where the values are a misture of scalars and ARRAYs.  If
there are any ARRAY to be found, the resulting value will be an ARRAY,
otherwise it will be a scalar with all the incoming valued joined
together with the separator given as first argument to add/add_before.

Move the documentation of the target configuration form to
Configurations/README.

Move initial assembler object templates to
Configurations/00-BASE-templates.conf.

Furthermore, remove all variables containing the names of the
non-assembler object files and make a BASE template of them instead.
The  values from this templates are used as defaults as is.  The
remaining manipulation of data when assembler modules are used is done
only when $no_asm is false.

While doing this, clean out some other related variables that aren't
used anywhere.

Also, we had to move the resolution of the chosen target a bit, or the
function 'asm' would never catch a true $no_asm...  this hasn't
mattered before we've moved it all to the BASE template, but now it
does.

At the same time, add the default for the 'unistd' key to the BASE
template.

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

This change is made to bring clarity, to have the two less

installation.

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.

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.

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

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!
