Start simple, removed some unused variables and change all '<<EOF' to
'<<"EOF"'.  The latter is because some code colorizers (notably, in
emacs) cannot recognise the here document end marker unless it's
quoted and therefore assume the rest of the file is part of the here
document.

For BSD systems, Configure adds a shared_ldflags including a reference
to the Makefile variable LIBRPATH, but since it must be passed down to
Makefile.shared, care must be taken so the value of LIBRPATH doesn't
get expanded too early, or it ends up giving an empty string.

Some users want to disable SSL 3.0/TLS 1.0/TLS 1.1, and enable just
TLS 1.2.  In the future they might want to disable TLS 1.2 and
enable just TLS 1.3, ...

This commit makes it possible to disable any or all of the TLS or
DTLS protocols.  It also considerably simplifies the SSL/TLS tests,
by auto-generating the min/max version tests based on the set of
supported protocols (425 explicitly written out tests got replaced
by two loops that generate all 425 tests if all protocols are
enabled, fewer otherwise).

We required that a target be named 'debug-something' or to have at
least one of the configuration items debug_cflags and debug_lflags for
--debug to be accepted.

However, there are targets with no such markings but that will still
have debugging capabilities.  This is particularly true for mk1mf
builds, where the extra flags for debugging are figured out later on
by util/mk1mf.pl.

For some strange reason opensslconf.h was only defining DES_LONG
when included via des.h, but that's exceedingly fragile (as a
result of include guards the include via des.h might not actually
process the content again).

Ripped out the nesting constraint, now always define OSSL_DES_LONG
if not already defined.  Note, this could just be DES_LONG, but
trying to avoid exposing DES_LONG in places where it has never been
seen before, so it is up to des.h to actually define DES_LONG as
OSSL_DES_LONG.

Configure has, so far, had no control at all of which 'no-' options it
can be given.  This means that, for example, someone could configure
with something absurd like 'no-stack' and then watch the build crumble
to dust...  or file a bug report.

This introduces some sanity into the possible choices.

The added list comes from looking for the explicit ones used in
Configure, and from grepping after OPENSSL_NO_ in all source files.
