  *) mod_md: when MDMessageCmd for a 'challenge-setup:<type>:<dnsname>'
     fails (!= 0 exit), the renewal process is aborted and an error is
     reported for the MDomain. This provides scripts that distribute
     information in a cluster to abort early with bothering an ACME
     server to validate a dns name that will not work. The common
     retry logic will make another attempt in the future, as with
     other failures.
     Fixed a bug when adding private key specs to an already working
     MDomain, see <https://github.com/icing/mod_md/issues/260>.

  *) mod_md: fixed a bug in handling multiple parallel OCSP requests. These could
     run into an assertion which terminated (and restarted) the child process where
     the task was running. Eventually, all OCSP responses were collected, but not
     in the way that things are supposed to work.
     See also <https://bz.apache.org/bugzilla/show_bug.cgi?id=65567>.
     The bug was possibly triggered when more than one OCSP status needed updating
     at the same time. For example for several renewed certificates after a server
     reload.

Merge r1890605, r1893164, r1893179 from trunk:

  *) core/mod_proxy/mod_ssl:
     Adding `outgoing` flag to conn_rec, indicating a connection is
     initiated by the server to somewhere, in contrast to incoming
     connections from clients.
     Adding 'ap_ssl_bind_outgoing()` function that marks a connection
     as outgoing and is used by mod_proxy instead of the previous
     optional function `ssl_engine_set`. This enables other SSL
     module to secure proxy connections.
     The optional functions `ssl_engine_set`, `ssl_engine_disable` and
     `ssl_proxy_enable` are now provided by the core to have backward
     compatibility with non-httpd modules that might use them. mod_ssl
     itself no longer registers these functions, but keeps them in its
     header for backward compatibility.
     The core provided optional function wrap any registered function
     like it was done for `ssl_is_ssl`.

  *core: clarify comments and use hook API better to check for presence of callbacks.

 * optimizing hook check as suggested by Yann.

Merge r1892740, r1892851 from trunk:

mod_proxy: Fix potential tunneling infinite loop and spurious timeout.
           PRs 65521 and 65519.

* modules/proxy/proxy_util.c(ap_proxy_tunnel_run):
  Avoid an infinite loop by shutting down the connection for write when poll()
  returns POLLHUP and read is already down.  PR 65521.

* modules/proxy/proxy_util.c(ap_proxy_tunnel_run):
  When write completion is finished don't check for ap_filter_input_pending()
  before proxy_tunnel_forward() to flush input data, this is a nonblocking read
  already which will do the same thing implicitely. ap_filter_input_pending()
  is broken in 2.4.x without the whole pending data mechanism (not backported
  yet), so let's align here.  PR 65519.

mod_proxy: Follow up to r1892740.

Really remove the old ap_filter_input_pending() handling forgotten by r1892740.

Merge of r1890693,r1890696 from trunk:

mod_ssl: tighten the handling of ALPN for outgoing (proxy)
     connections. If ALPN protocols are provided and sent to the
     remote server, the received protocol selected is inspected
     and checked for a match. Without match, the peer handshake
     fails.
     An exception is the proposal of "http/1.1" where it is
     accepted if the remote server did not answer ALPN with
     a selected protocol. This accomodates for hosts that do
     not observe/support ALPN and speak http/1.x be default.
