$(SHLIB_MAJOR).$(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'

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.

For consistency, it's better to use the perl that was specified to
Configure last time it was called.

Use case:

perl v5.8.8 was first along $PATH, perl v5.22.2 was available and
specified as: PERL=/opt/local/bin/perl ./config.  When make wanted to
reconfigure and called './Configure reconf', configuration broke down,
complaining about a perl that's too old.

Before OpenSSL 1.1.0, binaries were installed in a non-standard
location by default, and runpath directories were therefore added in
those binaries, to make sure the executables would be able to find the
shared libraries they were linked with.

With OpenSSL 1.1.0 and on, binaries are installed in standard
directories by default, and the addition of runpath directories is
therefore not needed any more.

Note that it relies on a trick from Configure, where file names for
object files made from C++ source get '.cc' replaced with '_cc.o' to
recognise them.  This is needed so the correct compiler is used when

The background story is that util/shlib_wrap.sh was setting LD_PRELOAD
or similar platform dependent variables, just in case the shared
libraries were built with -rpath.  Unfortunately, this doesn't work
too well with asan, msan or ubsan.

So, the solution is to forbid the combination of shared libraries,
-rpath and any of the sanity analyzers we can configure.

This changes util/shlib_wrap.sh so it only contains the code that sets
LD_PRELOAD when -rpath has been used when configuring.

In the case of using an independent makedepend, we had split that into
two separate recipes, one depending on the other.  However, there are
cases where the makedepend recipe was always trying, but doesn't
update the time stamp of the .d file because there are no actual
changes, and thereby causing constant updates of the object files.

This change makes one recipe that takes care of both makedepend och
cc, thereby avoiding these extra updates.
