Fix leak in ERR_get_state() when OPENSSL_init_crypto() isn't called yet

If OPENSSL_init_crypto() hasn't been called yet when ERR_get_state()
is called, it need to be called early, so the base initialization is
done.  On some platforms (those who support DSO functionality and
don't define OPENSSL_USE_NODELETE), that includes a call of
ERR_set_mark(), which calls this function again.
Furthermore, we know that ossl_init_thread_start(), which is called
later in ERR_get_state(), calls OPENSSL_init_crypto(0, NULL), except
that's too late.
Here's what happens without an early call of OPENSSL_init_crypto():

    => ERR_get_state():
         => CRYPTO_THREAD_get_local():
         <= NULL;
         # no state is found, so it gets allocated.
         => ossl_init_thread_start():
              => OPENSSL_init_crypto():
                   # Here, base_inited is set to 1
                   # before ERR_set_mark() call
                   => ERR_set_mark():
                        => ERR_get_state():
                             => CRYPTO_THREAD_get_local():
                             <= NULL;
                             # no state is found, so it gets allocated!!!!!
                             => ossl_init_thread_start():
                                  => OPENSSL_init_crypto():
                                       # base_inited is 1,
                                       # so no more init to be done
                                  <= 1
                             <=
                             => CRYPTO_thread_set_local():
                             <=
                        <=
                   <=
              <= 1
         <=
         => CRYPTO_thread_set_local()      # previous value removed!
    <=

Result: double allocation, and we have a leak.

By calling the base OPENSSL_init_crypto() early, we get this instead:

    => ERR_get_state():
         => OPENSSL_init_crypto():
              # Here, base_inited is set to 1
              # before ERR_set_mark() call
              => ERR_set_mark():
                   => ERR_get_state():
                        => OPENSSL_init_crypto():
                             # base_inited is 1,
                             # so no more init to be done
                        <= 1
                        => CRYPTO_THREAD_get_local():
                        <= NULL;
                        # no state is found, so it gets allocated
                        # let's assume we got 0xDEADBEEF
                        => ossl_init_thread_start():
                             => OPENSSL_init_crypto():
                                  # base_inited is 1,
                                  # so no more init to be done
                             <= 1
                        <= 1
                        => CRYPTO_thread_set_local():
                        <=
                   <=
              <=
         <= 1
         => CRYPTO_THREAD_get_local():
         <= 0xDEADBEEF
    <= 0xDEADBEEF

Result: no leak.

Build file templates: Replace the use of Makefile.shared

Because this also includes handling all sorts of non-object files when
linking a program, shared library or DSO, this also includes allowing
general recognition of files such as .res files (compiled from .rc
files), or .def / .map / .opt files (for export and possibly
versioning of public symbols only).

This does mean that there's a tangible change for all build file
templates: they must now recognise and handle the `.o` extension,
which is used internally to recognise object files internally.  This
extension was removed by common.tmpl before this change, but would
mean that the platform specific templates wouldn't know if "foo.map"
was originally "foo.map.o" (i.e. an object file in its own right) or
"foo.map" (an export definition file that should be treated as such,
not as an object file).

For the sake of simplifying things, we also modify util/mkdef.pl to
produce .def (Windows) and .opt (VMS) files that don't need additional
hackery.

chacha/asm/chacha-x86_64.pl: add AVX512VL code path.

256-bit AVX512VL was estimated to deliver ~50% improvement over AVX2
and it did live up to the expectations.

crypto/x86_64cpuid.pl: suppress AVX512F flag on Skylake-X.

It was observed that AVX512 code paths can negatively affect overall
Skylake-X system performance. But we are talking specifically about
512-bit code, while AVX512VL, 256-bit variant of AVX512F instructions,
is supposed to fly as smooth as AVX2. Which is why it remains unmasked.

Save away the environment variables we rely on

There are cases when we overwrite %ENV values, and while this is
perfectly fine on some platforms, it isn't on others, because the
Configure script isn't necessarely run in a separate process, and
thus, changing %ENV may very well change the environment of the
calling shell.  VMS is such a platform.

Furthermore, saving away values that we use also allow us to save them
in configdata.pm in an effective way, and recall those values just as
effectively when reconfiguring.  Also, this makes sure that we do use
the saved away values when reconfiguring, when the actual environment
variables might otherwise affect us.
