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.

Don't include "\" in the printable form of the data because
it will be escaped later in processing, and the extra escaping
throws off the alignment. Just filter it out like unprintable
characters.

Make sure an error log provider has initialized before trying to log to it.
(A log function may be called in a window between closing stderr and opening logs.)

- set stderr_log to NULL after it is redirected to /dev/null
- use log provider of ap_server_conf in log_error_core when no server_rec
is provided and std_err_log is NULL

Initialize error log providers in vhosts, solving crashes
when logging from those vhosts as well as allowing a different
provider (or provider configuration) for vhosts.

optionally modified by a module when the effective IP of the client
is not the same as the real IP of the client (such as a load balancer).

everywhere.
We know that the core module has module_index 0. Therefore we can save
some pointer operations in ap_get_module_config(cv, &core_module) and
ap_set_module_config(cv, &core_module, val). As these are called rather often,
this may actually have some (small) measurable effect.

of the message is higher than a specified value. This allows to achive
the old behaviour for the source file name/line number of being only
logged for debug and higher.
