configure checks against a /usr installed OpenSSL and then link against
a different pkg-config installed OpenSSL.

(Hint: Try with Mac OS X with MacPorts's OpenSSL or FreeBSD w/OpenSSL ports.)

* acinclude.m4
  (APACHE_CHECK_SSL_TOOLKIT): Load in pkg-config variables first before doing
  any OpenSSL checks so that we don't clobber things later.

In both cases we already include SSL_LIBS, so lets add
the necessary link flags only to SSL_LIBS and not to
EXTRA_LDFLAGS.

The last of a series of changes of type
"restrict link dependencies where possible".

- Before, simple wouldn't start without explicit
  config, because default numbers were 0
- log messages "more" and "less" were misleading

It seems that's the way it is used for most modules,
so remove unnecessary explicit object file lists.

Also move '#error' after the includes, because it seems
CMSG_DATA is commonly defined in sys/socket.h.

The check also overwrites _apmod_error_fatal in case
CMSG_DATA is not defined to allow building when configure
was called with "--enable-proxy". Otherwise one would need
to explicitly disable mod_proxy_fdpass.

We might want to remove the #error completely, because the
new feature test prevents the building of the module when
the symbol is not defined.

at least do this beforehand...

For backport, this'll need an ABI-preserving version that'll be
a minor MMN bump.  But if we do that in /trunk/, it'll never change.
