case by using iteration instead of recursion.
We have a relatively small recursion limit of
about 10 operations. This is a compilation
limit (a define). It can be hit if many expr
vars or function calls are concatenated.
The new optimization is very similar to the
existing one, which optimizes consecutive
concatenations in node2 of the tree. The new
one optimizes consecutive concatenations in
node 1.

(parent directive).
Usually, this context is not also EXEC_ON_READ so it's not fully processed, so
e.g cmd->path is not fluffed up yet because the closing tag
of the section is not read yet and ap_check_cmd_context()
doesn't work)

The code reverted attempted to restrict comparisons of the r->filename
to given DirectoryMatch blocks.
r->filename was already a non-directory entity at this point, because we
have already fallen out of the } while (thisinfo.filetype == APR_DIR);
block above.
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.

Retain num_buckets and max_buckets accross restarts so that we can determine
whether new buckets were allocated and set their idle_spawn_rate at the same
level as the existing ones (max).
Also, adjust ap_daemons_limit and ap_daemons_to_start lower bounds at mpm_run()
time, once num_buckets is available for the current generation (previously done
at check_config time, hence before num_buckets is computed, and then with the
previous generation's value).

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
CPU cores).
