svn up to r1775787. Not that I intended it, and absolutely not the way we
should apply it (revert layer by layer 6 commits replicated on the merge

Resigning my first attempt to get patches through the 2.2.x process, and
revoking my ratification of a list of patches (e.g. -1 as had been applied,
including my own submissions - I will revert in any case, where misordered.)

Proposing that we start with the same branch model as used on 2.4.x to get
through too many many-year-old patches to idly browse through; replay these
in mostly-sequential order, and bring 2.2.x up to 2.4.x in the affected areas
of code, and finally this proposal suggests the same merge as was applied to
2.4.25 GA release, modulo all our new crazy APLOGNO fun.

There is not much to see here, other than to compare rev no's of what had
been applied/proposed reverts to the list of patches on the 2.2.x merge
branch... the interesting data is on that merge branch. But extensive testing
against the resulting code is critical to our hope of offering a last 2.2.x
release to close that chapter. TIA to each and everyone who assists!

Merge r1710095, r1727544 from trunk:

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.

* Ensure that proto_num and protocol is set in another "error out early" edge
  case. This can happen with invalid CONNECT requests as described in the PR.
