HAProxy 1.9-dev5 was released on 2018/10/28. It added 58 new commits
after version 1.9-dev4.

This version continues to merge new features and addresses some issues
that came in -dev4 regarding stream processing. For now it's working
rather well given the complexity of the changes, eventhough we still
expect to resurrect some deeply burried issues due to the significant
change of I/O scheduling.

Among the new features merged, I can list these ones :
  - when running in master/worker mode, the master can now have its own
    CLI socket, and implements a proxy able to connect to all worker
    processes. It will even be able to reach older processes soon, so
    that we can kill an old cnonection preventing an old process from
    quitting, or simply figure why an old process doesn't quit. Some
    more updates are coming on this part (prompt will be disabled by
    default, older processes not joinable now, some doc etc).

  - the HTTP small object cache can now cache objects larger than a
    buffer. The new size limit defaults to 1/256 of the cache size but
    can be changed with "max-object-size".

  - the cache now implements the Age HTTP header field.

The rest is mostly infrastructure updates for the upcoming code, and
fixes for various issues. It's worth noting that Lukas has addressed
an interesting issue with HTTP authentication where the private
connection mistakenly had precedence over the load balancing algorithm
in order to cover NTLM/Negotiate. This one will be backported to 1.8.

Developers might like the addition of the ERR variable to the makefile
to automatically add -Werror.

For now what I'm seeing overall looks pretty good. We've again put the
finger on some old stuff around the stream interface flag SI_FL_WAIT_ROOM,
which we expected could easily replace channel_may_recv(), until the old
dirty zombies in the code decided to fight back :-)  It's the first time
I've seen a 3-hours 3-person meeting dedicated to a single flag! But I
think we've found how to address this old crap so that we can rebase the
changes related to the internal native HTTP representation (codenamed HTX).

I'll try to issue -dev6 next week-end, eventhough this week will be short
for some of us. Ideally if we could merge the HTX code next week-end, we
could then switch to testing and debugging to stabilize all this stuff.
