Take care not to call ap_start_lingering_close from the listener thread,
because it may block when flushing data to the client.

From the listener thread, do a lingering close without flushing. This is
OK because we only do this if there has been an error during write
completion or if our send buffers are empty because we are in keep-alive.

mpm_event, mpm_worker: Fix cases where the spawn rate wasn't reduced
after child process resource shortages.

The broken scenario:

  child X exits with APEXIT_CHILDSICK
  another child Y is created and reuses child X's scoreboard slot
  child X's exit status is processed

The case that worked is when child X's scoreboard slot hadn't
been reused by the time that its exit status was processed.

- Do the counting in the connection pool cleanup to ensure that it gets
