Deregister all hooks first (in pre_cleanup), by doing it last we could still
have had them run when DSOs were unloaded.

Likewise, avoid double faults when handling fatal signals by restoring the
default handler before pconf is cleared (we can't ap_log_error there).

Finally, we need to ignore sig_term/restart (do nothing) when the main
process is exiting (i.e. ap_pglobal is destroyed), since retained_data are
freed.

                   context.

This change is an attempt to fix a long standing problem,
brought up while working on PR 58231. Our documentation clearly
states the following:

"If a HTTP header is used in a condition this header is added
to the Vary header of the response in case the condition
evaluates to true for the request."

This is currently not true for RewriteCond/Rules working in
a directory context, since when an internal redirect happens
all the outstanding response headers get dropped.

There might be a better solution so I am looking forward to
hear more opinions and comments. My goal for a delicate change
like this one would be to affect the least amount of configurations
possible, without triggering unwanted side effects.

If the solution is good for everybody tests will be written
in the suite asap.

      mod_rewrite/core: avoid the 'Vary: Host' header

In PR 58231 is was brought up that httpd adds the
Vary: Host header whenever a condition is set to true
in mod_rewrite or in an <If> block.

The https://tools.ietf.org/html/rfc7231#section-7.1.4
section seems to disallow this use case:

"The "Vary" header field in a response describes "
"what parts of a request message, "
"aside from the method, Host header field, [...]"

I had a chat with the folks in #traffic-server and
they don't see much point in having a Vary: Host header,
plus it was reported that Varnish doesn't like it very
much (namely it does not cache the response when
it sees the header, links of the report in the PR).

I don't see much value in this behavior of httpd so
I am inclined to remove this response header value,
but I'd be glad to get a more experienced opinion.



mod_rewrite,core: avoid Vary:Host (part 2)

This is a follow up of r1808746 after a chat
with Yann on dev@:

- the HTTP:Host variable suffers from the same problem
- the strcasecmp should be used to allow case-sensitive
  comparisons.
- in mod_rewrite is less cumbersome and more clean to just
  make the Host header check in lookup_header, so it will
  be automatically picked up by every part of the code
  that uses it. It shouldn't be a relevant overhead for
  mod_rewrite.

      mod_ssl: return non ambiguous value in ssl_callback_SessionTicket() for
encryption mode (we used to return 0, OpenSSL documents returning 1 instead).

Practically this does not change anything since OpenSSL will only check for
>= 0 return value (non error) for encryption mode (the other possible return
values are only relevant for decryption mode).

However the OpenSSL documentation for SSL_CTX_set_tlsext_ticket_key_cb()
states:
"
The return value of the cb function is used by OpenSSL to determine what
further processing will occur. The following return values have meaning:

2
    This indicates that the ctx and hctx have been set and the session can
    continue on those parameters. Additionally it indicates that the session
    ticket is in a renewal period and should be replaced. The OpenSSL library
    will call cb again with an enc argument of 1 to set the new ticket (see
    RFC5077 3.3 paragraph 2).

1
    This indicates that the ctx and hctx have been set and the session can
    continue on those parameters.

0
    This indicates that it was not possible to set/retrieve a session ticket
    and the SSL/TLS session will continue by by negotiating a set of
    cryptographic parameters or using the alternate SSL/TLS resumption
    mechanism, session ids.
    If called with enc equal to 0 the library will call the cb again to get a
    new set of parameters.

less than 0
    This indicates an error.
"

So 0 is not appropriate in our code, 1 is what we really want (and it won't
break if OpenSSL later changes its checks on the callback return value).

      event: Avoid possible blocking in the listener thread when shutting down
connections. PR 60956.

start_lingering_close_nonblocking() now puts connections in defer_linger_chain
which is emptied by any worker thread (all atomically) after its usual work,
hence any possibly blocking flush and lingering close run outside the listener.

The listener may create a dedicated worker if it fills defer_linger_chain or
while it's not empty, calling push2worker with a NULL cs.

The state machine in process_socket() is slighly modified to be able to enter
with CONN_STATE_LINGER directly w/o clogging_input_filters to interfer.

New abort_socket_nonblocking() allows to reset connections when nonblocking is
required and we can't do much about the connection anymore, nor we want the
system to linger on its own after close().

Many thanks to Stefan Priebe for his heavy testing on many event's changes!
