- mod_authn_socache.c: fix creation of default socache_instance.
- add Note how the OpenSSL version used to build httpd is found (apr-1-config)
Upstream r1576233 commit message
In pre_config, default socache_provider is created, but socache_instance
initialization is missing. This leads to crash on startup if default
socache_provider is used (AuthnCacheSOCache is not called) and
AuthnCacheEnable or AuthnCacheProvideFor is used.
