Abort the client or backend connection on polling errors, but don't forcibly
abort the client side at the end (the core filters will do that otherwise
when necessary), so that lingering close and SSL shutdown can occur on normal
close.

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 o...
