Merge of /httpd/httpd/trunk:r1893399

  *) 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 r1893001, r1893002, r1893004 from trunk:

core: Set r->request_time before any logging, mod_unique_id needs it.

* server/protocol.c(read_request_line):
  Move r->request_time initialization before first APLOG_TRACE5,
  ap_log_rerror() may run the generate_log_id hooks and call mod_unique_id
  with no timestamp initialized (zero).

mod_unique_id: Follow up to r1892915: Shorter counter race condition yet.

* modules/metadata/mod_unique_id.c(gen_unique_id):
  Set the counter in network byte order for uuencoding only, allowing for
  simple cur_unique_id.counter++

mod_unique_id: Follow up to r1892915 and r1893002: Atomic counter.

* modules/metadata/mod_unique_id.c(gen_unique_id):
  Use an atomic 32bit counter to close the race condition with threaded MPMs,
  using the lower 16 bits for uuencoding still.

Merge r1893016 from trunk:

mod_proxy: Don't canonicalize with both nocanon and ProxyPassInterpolateEnv On.

If nocanon is set, we should match the unparsed_uri against the interpolated
alias (not the ProxyPass'ed one) when verifying the resulting length. Otherwise
we falsely restore the canonicalized URL in case of mismatch.  PR 65549.

The number of children spawned can go above active_daemons_limit due to
exponential idle_spawn_rate growth (x 2), enforce the upper limit in

Submitted by: Joel Self <joelself gmail.com>

mpm_event: Follow up to r1893014: log when children are not spawned.

Log at trace1 level when active_daemons >= active_daemons_limit and we won't
spawn children. Reset free_length to avoid negative value in this case too.
