Use short lived pool to avoid memory leaks

Remove the comment about binding upstream and downstream connections. It
seems to be obsolete since r104604, r104605, r105108.

Also avoid allocating memory if we are not handling the connection.

mod_proxy_balancer: Restore balancing after a failed worker has
recovered when using lbmethod_bybusyness.

PR: 48735

Markus Stoll and Adam C both submitted patches against 2.2.x
to bug 48735.  Compared with those two, this solution

1. resets the busy field in the error-ed worker at the end of
   the request instead of at recovery time
2. leaves the lbstatus field alone
3. covers all possible scenarios where the busy field in the
   error-ed worker needs to be adjusted, since a cleanup to
   perform the decrement is registered at the point of the
   increment

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.

after child process resource shortages.

The broken scenario:

  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
