commit e863f544f94a4435bcd9d4b98760f99d200c3407

Refactor the Acceptor to make the stop on wait optional/configurable
This is some preparatory work towards a fix for BZ 64080.
https://bz.apache.org/bugzilla/show_bug.cgi?id=64080
I need to be able to signal the Acceptor to stop without having to wait
for the stop to complete.
