ab: Fix maintenance of the pollset to resolve EINPROGRESS errors with kqueue (BSD/OS X) and excessive CPU with event ports (Solaris). The apr_pollset API requires that a socket be removed from the pollset whenever there is a change to the requested events. The socket must also be removed when it is closed. This wasn't completely implemented. PR: 44584
