We're currently using the attributes 'defines', 'cppflags', 'cflags'
etc quite liberally, with no regard for where that ends up.  Quite a
few of those flags are actually only relevant for the libraries
(mostly libcrypto), so it's safe to say that those could be applied to
the libraries only.

So, we move some of those flags to 'lib_defines', 'lib_cppflags',
'lib_cflags', etc.

With the support of "make variables" comes the possibility for the
user to override them.  However, we need to make a difference between
defaults that we use (and that should be overridable by the user) and
flags that are crucial for building OpenSSL (should not be
overridable).

Typically, overridable flags are those setting optimization levels,
warnings levels, that kind of thing, while non-overridable flags are,
for example, macros that indicate aspects of how the config target
should be treated, such as L_ENDIAN and B_ENDIAN.

We do that differentiation by allowing upper case attributes in the
config targets, named exactly like the "make variables" we support,
and reserving the lower case attributes for non-overridable project
flags.

Most modules are direct implementations of openssl application
sub-commands, but some constitute a support library, which can be used
by more than one program (and is, incidently, by test/uitest).

For practical purposes, we place the support library modules in a
private, static library.

Finally, there are some modules that don't have direct references in
the rest of the apps code, but are still crucial.  See them as some
kind of extra crt0 or similar for your platform.

Ideally, each config target should inherit a base to get their
platform specific defaults.  Unfortunately, that is currently not the
case, so we duplicate the Unixly defaults from the BASE_unix template
into the DEFAULT template.

C preprocessor flags get separated from C flags, which has the
advantage that we don't get loads of macro definitions and inclusion
directory specs when linking shared libraries, DSOs and programs.

This is a step to add support for "make variables" when configuring.

So far, we've placed all extra library related flags together, ending
up in the make variable EX_LIBS.  This turns out to be problematic, as
for example, some compilers don't quite agree with something like
this:

    cc -o foo foo.o -L/whatever -lsomething

They prefer this:

    cc -L/whatever -o foo foo.o -lsomething

IBM's compiler on OS/390 is such a compiler that we know of, and we
have previously handled that as a previous case.

The answer here is to make a more general solution, where linking
options are divided in two parts, where one ends up in LDFLAGS and
the other in EX_LIBS (they corresponds to what is called LDFLAGS and
LDLIBS in the GNU world)

It will return the last expression from the input file.

We also use this in read_config, which slightly changes what's
expected of Configurations/*.conf.  They do not have to assign
%targets specifically.  On the other hand, the table of configs MUST
be the last expression in each of those files.

The macros ZLIB and ZLIB_SHARED weren't appropriately defined,
deviating wrongly from how they worked in earlier OpenSSL versions.
So, restore it so that ZLIB is defined if configured "enable-zlib" and
so that ZLIB and ZLIB_SHARED are defined if configured
"enable-zlib-dynamic".

Additionally, correct the interpretation of the --with-zlib-lib value
on Windows and VMS, where it's used to indicate the actual zlib
zlib library file / logical name, as that can differ depending on zlib
version and packaging on those platforms.

Finally for Windows and VMS, we also define the macro LIBZ with that
file name / logical name when configured "zlib-dynamic", so the
compression unit can pick it up and use it.

The thread_cflag setting filled a double role, as kinda sorta an
indicator of thread scheme, and as cflags.  Some configs also added
lflags and ex_libs for multithreading regardless of if threading would
be enabled or not.

Instead of this, add threading cflags among in the cflag setting,
threading lflags in the lflag setting and so on if and only if threads
are enabled (which they are by default).

Also, for configs where there are no special cflags for threading (the
VMS configs are of that kind), this makes it possible to still clearly
mention what thread scheme is used.

The exact value of thread scheme is currently ignored except when it's
"(unknown)", and thereby only serves as a flag to tell if we know how
to build for multi-threading in a particular config.  Yet, the
currently used values are "(unknown)", "pthreads", "uithreads" (a.k.a
solaris threads) and "winthreads".

Instead, make the build type ("debug" or "release") available through
$config{build_type} and let the configs themselves figure out what the
usual settings (such as "cflags", "lflags" and so on) should be
accordingly.

The benefit with this is that we can now have debug and release
variants of any setting, not just those Configure supports, and may
also involve other factors (the MSVC flags /MD[d] and /MT[d] involve
both build type and whether threading is enabled or not)

Configure had the Unix centric addition of -lz when linking with zlib

it to the BASE_unix config template and add corresponding ones in the
other BASE_* config templates.  The Windows one is probably incomplete,
but that doesn't matter for the moment, as mk1mf does it's own thing
anyway.

This required making the %withargs table global, so perl snippets in
