File::Glob::glob is deprecated, it's use generates this kind of
message:

    File::Glob::glob() will disappear in perl 5.30. Use File::Glob::bsd_glob() instead. at ../master/Configure line 277.

So instead, use a construction that makes the caller glob() use
File::Glob::bsd_glob().

Note that we're still excluding VMS, as it's directory specs use '['
and ']', which have a different meaning with bsd_glob and would need
some extra quoting.  This might change, but later.

Instead of setting a "magic" global variable to force RAND to keep
consistent state and always generate the same bytestream, have
the fuzzing code install its own RAND_METHOD that does this.  For
BN_RAND_DEBUG, we just don't do it; that debugging was about mucking
with BN's internal representation, not requiring predictable rand
bytes.

$(SHLIB_MAJOR).$(SHLIB_MINOR) is really a synonym for
$(SHLIB_VERSION_NUMBER), and is therefore an added complexity,
so better to use $(SHLIB_VERSION_NUMBER) directly.  SHLIB_MAJOR and
SHLIB_MINOR are now unused, but are kept around purely as information
in case someone relies on their existence.

At the same time, add support for custom shared library extensions
with the three new Makefile variables SHLIB_EXT, SHLIB_EXT_SIMPLE and
SHLIB_EXT_IMPORT.  By default, they hold the variants of shared
library extensions we support.  On mingw and cygwin, SHLIB_EXT_IMPORT
is defined; on all other Unix platforms, it's empty.

An example to get shared libraries with a slightly different SOVER name:

    $ make SHLIB_EXT='.$(SHLIB_VERSION_NUMBER).so'

OpenSSL already has the feature of SSL_MODE_RELEASE_BUFFERS that can
be set to release the read or write buffers when data has finished
reading or writing. OpenSSL will automatically re-allocate the buffers
as needed. This can be quite aggressive in terms of memory allocation.

This provides a manual mechanism. SSL_free_buffers() will free
the data buffers if there's no pending data. SSL_alloc_buffers()
will realloc them; but this function is not strictly necessary, as it's
still done automatically in the state machine.

There's a case when the environment variable OPENSSL_CONF is
useless...  when cross compiling for mingw and your wine environment
has an environment variable OPENSSL_CONF.  The latter will override
anything that's given when starting wine and there make the use of
that environment variable useless in our tests.

Therefore, we should not trust it, and use explicit '-config' options
instead.

Makefile.shared was designed to figure out static library names,
shared library names, library version compatibility, import library
names and the like on its own.  This was a design for pre-1.1.0
OpenSSL because the main Makefile didn't have all that knowledge.

With 1.1.0, the situation isn't the same, a lot more knowledge is
included in the main Makefile, and while Makefile.shared did things
right most of the time (there are some corner cases, such as the
choice of .sl or .so as DSO extension on some HPUX versions), there's
still an inherent fragility when one has to keep an eye on
Makefile.shared to make sure it produces what the main Makefile
produces.

This change simplifies Makefile.shared by removing all its
"intelligence" and have it depend entirely on the input from the main
Makefile instead.  That way, all the naming is driven from
configuration data.
