Matt Caswell ff75a25749 Refactor the async wait fd logic
Implementation experience has shown that the original plan for async wait
fds was too simplistic. Originally the async logic created a pipe internally
and user/engine code could then get access to it via API calls. It is more
flexible if the engine is able to create its own fd and provide it to the
async code.

Another issue is that there can be a lot of churn in the fd value within
the context of (say) a single SSL connection leading to continually adding
and removing fds from (say) epoll. It is better if we can provide some
stability of the fd value across a whole SSL connection. This is
problematic because an engine has no concept of an SSL connection.

This commit refactors things to introduce an ASYNC_WAIT_CTX which acts as a
proxy for an SSL connection down at the engine layer.

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)
