There were a few environment variables that we supported in earlier
Configure versions which got transfered to the %user table. This
change makes sure that we still support them, by simply pre-populating
the corresponding %user entries with those environment values.

Configure: Don't fail if there were "make variables" set in env

The original intent was that if someone had a "make variable" set in
any kind of way, be it as an environment variable or as an argument to
Configure, we wouldn't allow compiler or linker flags as arguments as
well. That made both of these configurations equivalently impossible:

./Configure target CFLAGS=-foo -lextra

CFLAGS=-foo ./Configure target -lextra

While this makes things look nice and consistent, real world use makes
this hard, as many projects where OpenSSL is a component also set
these variables for other components that use GNU autotools.

Therefore, we need to adapt our Configure accordingly. By
consequence, the two Configure lines above will not be equivalent any
more:

./Configure target CFLAGS=-foo -lextra

This command line will still fail, because the "make variable" was
given as a command line argument. This cannot be a mistake and is
therefore not allowed.

CFLAGS=-foo ./Configure target -lextra

This command line will work, but because there is a linker flag as
a command line argument, the environment (i.e. CFLAGS) is ignored.
That isn't quite consistent with the previous command, but is the old
Configure behavior, before the support for "make variables" was added,
and is therefore the backward compatible behavior.

Configure: allow to enable afalgeng if target does not start with Linux

The Debian build system uses a `debian' target which sets CFLAGS and
then we have for instance debian-amd64 which inherits from
linux-x86_64 and debian [0]. So far so good.

Unless there are different suggestions how to do this, I would keep it.
However since the target name does not start with `linux', the build
system does not enable the afalg engine. So in order to get enabled, I
added a
`enable => [ "afalgeng" ],'
to the generic linux config which sets it explicit (as suggested by
Richard Levitte). Having this set, we can check for it instead matching
the target name.

Configure: catch the build tree configdata.pm

There are things depending on configdata.pm. However, it's perfectly
possible that there is one in the source directory from a previous
build, and that might disrupt an out of source build. To avoid this
conflict, make sure never to use the source tree configdata.pm in that
case, i.e. make the hard assumption that it's a generated file in the
build tree, which it is.

Configure et al: Move the definition of library only flags

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.

Configure: correct the check of env vars vs command line flags

The check to detect if env / make variables conflicted with compiler /
linker flags on the configure command line went a little too far, and
would stop the configuration process if any such command line flag was
given, with no regard for the env / make variables at all.

This change refines the check so the stop only gets triggered if any
such flags were given AND any of the corresponding variables are set.

Make "make variables" config attributes for overridable flags

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.

Configure et al: rename all dso_* to module_* in shared-info.pl

Because there are already attributes with the dso_ prefix that are

addition to them, it gets confusing to have similar or exactly the
same attributes working with different semantics on Unix.

So we rename those by changing the prefix dso_ to module_, and having
those work just like the shared_ attributes, but for DSOs.
