Merge r1225197:

Adapt loglevel of config errors during second pass

Don't use APLOG_STARTUP since at that point, the error log is already
available. This gives us timestamps if these errors happen during graceful
restart.

Use level 'emerg' as these errors are fatal.

SSLProtocol: allow explicit control of TLSv1.1 and TLSv1.2 flavors when
compiled against OpenSSL 1.0.1 or later. Update documentation.

merge r1222917 from trunk:

Set OPENSSL_NO_SSL_INTERN when compiling against OpenSSL 1.0.1
or later, so that mod_ssl retains binary compatibility with future
versions when internal structures are changed. Use API functions
where available, and fall back to direct access for OpenSSL up
to 1.0.0, where needed.

Remove SSL_make_ciphersuite() from ssl_util_ssl.[ch], as it was
never used by any released version of mod_ssl.

merge r1222915 from trunk:

REMOTE_ADDR is now r->useragent_ip, which is not/never available at
SSL_CB_HANDSHAKE_DONE time. ap_log_cerror() already logs c->client_ip
for us, however, so we can simply drop REMOTE_ADDR from the message.

Backport:
mod_mime: Don't arbitrarily bypass AddOutputFilter during a ProxyPass,
