virtual host which handled the latest request on the connection, or by
default the one of the first virtual host bound to the same IP:port.
For non-async MPMs, use either r->server's or c->base_server's value in
ap_process_http_sync_connection() depending on a new server_rec's flag
called keep_alive_timeout_set and determined at config time.
For event MPM, use a queue per timeout value, chaining the queues per
type (keepalive wrt KeepAliveTimeout, write completion wrt to Timeout)
so that maintenance can be done on all the queues from the head, and such
that insertions/maintenance remain in O(1).
A server config is created and pointing to the queue of each vhost at
post_config time, hence the config can be associated to the connection
state (cs) at post_read_request time (keep_alive_timeout_set is used to
determine r->server vs c->base_server here), and we can simply insert
with TO_QUEUE_INSERT(cs->sc->q, cs). PR56226.
While at it, since each queue now embeds it own timeout and hence the
expiration_time of the cs has changed to a queue_timestamp (the time it
was queued), we can detect clock skews and expire entries immediatly if
the system is set (eg. far) in the past during runtime and we want to
avoid waiting for (eg.) centuries before the current logic kills them.
Any entry which is registered above now + q->timeout is concerned, and
is now cleaned from the queue when encountered. PR57374.

r->filename was already a non-directory entity at this point, because we

The addition of r->d_is_directory was redundant. That is what is always
returned by ap_get_core_module_config(r->per_dir_config).
Note modifying dir_config required an MMN major bump as this commit could
have realigned the offset of refs (had it been added to the end, this
would correspond to an mmn minor bump) and other fields packed into the
same bytes (this is undefined). Bump on revert to prevent unexpected crashes.

Add ListenCoresBucketsRatio which is a configurable ratio between the number of
CPU cores (online) and the number of listeners buckets to create, defaulting to
zero (so that listeners buckets become an opt-in, ie. ncpus / ratio > 1).
This could also be made an opt-out by using the previous hardcoded value (8) as
default.
Make ap_close_listeners() act on all the listeners (including duplicated ones),
since the function is also called externally (eg. mod_cgid, mod_ssl_ct and
possibly any third party module) to cleanup opened descriptors when a process
is forked (the duplicated listeners are kept in a scoped/static variable).
Add ap_close_listeners_ex() to close a single bucket of listeners, used by the
children to close unused duplicates and internally by ap_close_listeners().
Make ap_duplicate_listeners() compute the number of buckets to be used, instead
of each MPM. This number is now based on the above ratio and will not change
unless asked to (given *num_buckets < 1, that is when the MPM does not run in
one-process mode nor after a graceful restart).
Remove some global variables (mpm_listen, enable_default_listeners) previously
used to communicate between MPMs and ap_listen, since ap_duplicate_listeners()
API can now be used to do so.
Also rename num_buckets as ap_num_listen_buckets, and prefix have_so_reuseport
with ap_ (both printed by ap_log_common(), hence kept global).
Detect ap_have_so_reuseport once only at startup.
Restore dummy_connection() as before r1599531 since sending POD signals should
not depend on the number of listeners buckets (there is still one single socket
receiving the connections).
For each MPM (concerned), move the bucket data (pod, listeners and eventually
accept mutex) into a struct and instanciate an array of them (sized by the
number of buckets), for each child to use its own data according to its bucket
index, and the parent to maintain the whole.

and silently adjust the configured number of processes/threads to
be above the computed number of listener buckets (depending on the

core: HTTP trailers could be used to replace HTTP headers
late during request processing, potentially undoing or
otherwise confusing modules that examined or modified
request headers earlier. Adds "MergeTrailers" directive to restore
legacy behavior.
