      For the "SSLStaplingReturnResponderErrors off" case, make sure to only
staple responses with certificate status "good". Also avoids including
inaccurate responses when the OCSP responder is not completely up
to date in terms of the CA-issued certificates (and provides interim
"unknown" or "extended revoked" [RFC 6960] status replies).

Log a certificate status other than "good" in stapling_check_response().

Propagate the "ok" status from stapling_check_response() back via both
stapling_renew_response() and get_and_check_cached_response() to the
callback code in stapling_cb(), enabling the decision whether to include
or skip the response.

      core: Limit to ten the number of tolerated empty lines between request,
and consume them before the pipelining check to avoid possible response
delay when reading the next request without flushing.

Before this commit, the maximum number of empty lines was the same as
configured LimitRequestFields, defaulting to 100, which was way too much.
We now use a fixed/hard limit of 10 (DEFAULT_LIMIT_BLANK_LINES).

check_pipeline() is changed to check for (up to the limit) and comsume the
trailing [CR]LFs so that they won't be interpreted as pipelined requests,
otherwise we would block on the next read without flushing data, and hence
possibly delay pending response(s) until the next/real request comes in or
the keepalive timeout expires.
 
Finally, when the maximum number of empty line is reached in
read_request_line(), or that request line does not contains at least a method
and an (valid) URI, we can fail early and avoid some failure detected in
further processing.


core: follow up to r1710095.
Simplify logic in check_pipeline(), and log unexpected errors.

mod_ssl: don't FLUSH output (blocking) on read.
This defeats deferred write (and pipelining), eg. check_pipeline() is not
expecting the pipe to be flushed under it.
So let OpenSSL >= 0.9.8m issue the flush when necessary (earlier versions
are known to not handle all the cases, so we keep flushing with those).

PR 57641 [Marc.Stern]


mod_substitute: follow up r1684900.
Introduce the SubstituteInheritBefore directive to configure the merge order.
This allows to preserve 2.4 and earlier behaviour.


mod_substitute: follow up to r1687539.

wrowe's advices.


mod_substitute: follow up to r1687680.
Fix dir config merger 'over'-write, thanks Bill (again).

Very difficult to read, and therefore was wrong.

Assert that the SubstituteInheritBefore option was explicitly toggled,
and do not default in 2.x to this legacy behavior.



Optimize in all cases that the members are all explicitly initialized.

Useful for 2.2 and 2.4, but trunk will require the subsequent patch.




Increase legibility of the max_line_length behavior, and adjust for
the requirement that all members are initialized explicitly due to
the previous patch.



Net -8 LoC, my usual specialty.

This didn't need to be reinvented; please use established helpers.



mod_substitute: follow up r1688339.
SubstituteInheritBefore is the default in 2.5.x but wasn't for ealier versions.

      With the current implementation, it is likely to connect/close a socket with the memcache server for each command sent.
The root cause is a too small idle timeout (600 microseconds).

Add a new directive, 'MemcacheConnTTL',  to control this idle connection timeout with the memcache server(s).
Change the default value from 600 usec (!) to 15 sec as per Yann suggestion.

I've limited accepted values from 1 to 1800 seconds (half an hour) because internaly, the value passed to 'apr_memcache_server_create' is still in mirco-seconds.
