Now that we're using templates, we should warn people not to edit the
resulting file.  We do it through util/dofile.pl, which is enhanced
with an option to tell what file it was called from.  We also change
the calls so the template files are on the command line instead of
being redirected through standard input.  That way, we can display
something like this (example taken from include/openssl/opensslconf.h):

    /* WARNING: do not edit! */
    /* Generated by Configure from include/openssl/opensslconf.h.in */

It is time for Makefile.org to fold into the new regime and have a run

increasingly the center of build information, which is as it should
be.

Now that configdata.pm is the centre of information, use that instead

future development with different Makefile file names.

The code to read necessary configuration data from Makefile is retained

Also, the string variables $openssl_*, which were populated with cpp

Because we're using Text::Template and we know it's a non core Perl

With this changes comes the transfer module for with_fallback.

For our own convenience, we need a mechanism to be able to fall back
on bundled Perl modules.  It's a minimal package that's called like
this:

    use with_fallback qw(Module1 Module2 ...);

For each module, it will try to require them from the system
installation, and failing that, it will temporarly add external/perl
and try to require transfer::{ModuleName}.  It requires that each
bundled Perl modules is accompanied by a small transfer module
(external/perl/transfer/ModuleName.pm in our example) that knows
exactly what to load.

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.

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.
