Make it possible to have a separate and different perl command string
for installable scripts than we use when building, with the
environment variable HASHBANGPERL.  Its value default to the same as
the environment PERL if it's defined, otherwise '/usr/bin/env perl'.

Note: this is only relevant for Unix-like environments.

Once upon a time, there was chop, which somply chopped off the last
character of $_ or a given variable, and it was used to take off the
EOL character (\n) of strings.

... but then, you had to check for the presence of such character.

So came chomp, the better chop which checks for \n before chopping it
off.  And this worked well, as long as Perl made internally sure that
all EOLs were converted to \n.

These days, though, there seems to be a mixture of perls, so lines
from files in the "wrong" environment might have \r\n as EOL, or just
\r (Mac OS, unless I'm misinformed).

So it's time we went for the more generic variant and use s|\R$||, the
better chomp which recognises all kinds of known EOLs and chops them
off.

A few chops were left alone, as they are use as surgical tools to
remove one last slash or one last comma.

NOTE: \R came with perl 5.10.0.  It means that from now on, our
scripts will fail with any older version.

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 */

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.
