Fixed handling of already closed connections.

In limit_req, auth_delay, and upstream code to check for broken
connections, tests for possible connection close by the client
did not work if the connection was already closed when relevant
event handler was set.  This happened because there were no additional
events in case of edge-triggered event methods, and read events
were disabled in case of level-triggered ones.

Fix is to explicitly post a read event if the c->read->ready flag
is set.
