Viktor Dukhovni 6b01bed206 Support disabling any or all TLS or DTLS versions
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).

How to add recipes
==================

For any test that you want to perform, you write a script located in
test/recipes/, named {nn}-test_{name}.t, where {nn} is a two digit number and
{name} is a unique name of your choice.

Please note that if a test involves a new testing executable, you will need to
do some additions in test/Makefile.  More on this later.


Naming convetions
=================

A test executable is named test/{name}test.c

A test recipe is named test/recipes/{nn}-test_{name}.t, where {nn} is a two
digit number and {name} is a unique name of your choice.

The number {nn} is (somewhat loosely) grouped as follows:

05  individual symmetric cipher algorithms
10  math (bignum)
15  individual asymmetric cipher algorithms
20  openssl enc
25  certificate forms, generation and verification
30  engine and evp
70  PACKET layer
80  "larger" protocols (CA, CMS, OCSP, SSL, TSA)
90  misc


A recipe that just runs a test executable
=========================================

A script that just runs a program looks like this:

    #! /usr/bin/perl
    
    use OpenSSL::Test::Simple;
    
    simple_test("test_{name}", "{name}test", "{name}");

{name} is the unique name you have chosen for your test.

The second argument to `simple_test' is the test executable, and `simple_test'
expects it to be located in test/

For documentation on OpenSSL::Test::Simple, do
`perldoc test/testlib/OpenSSL/Test/Simple.pm'.


A recipe that runs a more complex test
======================================

For more complex tests, you will need to read up on Test::More and
OpenSSL::Test.  Test::More is normally preinstalled, do `man Test::More' for
documentation.  For OpenSSL::Test, do `perldoc test/testlib/OpenSSL/Test.pm'.

A script to start from could be this:

    #! /usr/bin/perl
    
    use strict;
    use warnings;
    use OpenSSL::Test;
    
    setup("test_{name}");
    
    plan tests => 2;                # The number of tests being performed
    
    ok(test1, "test1");
    ok(test2, "test1");
    
    sub test1
    {
        # test feature 1
    }
    
    sub test2
    {
        # test feature 2
    }
    

Changes to test/Makefile
========================

Whenever a new test involves a new test executable you need to do the
following (at all times, replace {NAME} and {name} with the name of your
test):

* among the variables for test executables at the beginning, add a line like
  this:

    {NAME}TEST= {name}test

* add `$({NAME}TEST)$(EXE_EXT)' to the assignment of EXE:

* add `$({NAME}TEST).o' to the assignment of OBJ:

* add `$({NAME}TEST).c' to the assignment of SRC:

* add the following lines for building the executable:

    $({NAME}TEST)$(EXE_EXT): $({NAME}TEST).o $(DLIBCRYPTO)
           @target=$({NAME}TEST); $(BUILD_CMD)
