Hi,

Today I have tried to recreate the WAF.

I received this error at build time.

Openssl is
---> Package openssl.x86_64 1:1.0.1e-60.el7_3.1 will be installed
---> Package openssl-devel.x86_64 1:1.0.1e-60.el7_3.1 will be installed

I thought this case is covert with this commit.

BUG/MEDIUM: ssl: Fix regression about certificates generation

Since the commit f6b37c67 ["BUG/MEDIUM: ssl: in bind line, ssl-options after
'crt' are ignored."], the certificates generation is broken.

To generate a certificate, we retrieved the private key of the default
certificate using the SSL object. But since the commit f6b37c67, the SSL object
is created with a dummy certificate (initial_ctx).

So to fix the bug, we use directly the default certificate in the bind_conf
structure. We use SSL_CTX_get0_privatekey function to do so. Because this
function does not exist for OpenSSL < 1.0.2 and for LibreSSL, it has been added
in openssl-compat.h with the right #ifdef.

[root@centos-512mb-fra1-01 haproxy-waf]# egrep OPENSSL_VERSION_NUMBER  
/usr/include/openssl/*
/usr/include/openssl/crypto.h:#define SSLEAY_VERSION_NUMBER     
OPENSSL_VERSION_NUMBER
/usr/include/openssl/opensslv.h:#define OPENSSL_VERSION_NUMBER  0x1000105fL

How can I help to fix this issue?
