      mod_cache_socache: Fix a possible cached entity body corruption when it
is received from an origin server in multiple batches and forwarded by
mod_proxy.

Upstream buckets should be setaside when saving response body (store_body),
but since those will finally be flatten in the cache buffer (commit_entity),
let's save them directly into the buffer to avoid heap allocation(s) and
the final copy.

      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: forward EOR (only) brigades to the core_output_filter().

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).

mod_substitute: Fix configuraton merge order.
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.
Use tristate single inherit_before variable instead of two, according to
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.


mod_substitute: follow up r1697013.
Update the doc.
