Commit 1e53fe0e70 changed background processes so that they use standard SIGHUP handler. Like that, this commit makes walreceiver use standard SIGHUP and SIGTERM handlers, to simplify the code. As the side effect of this commit, walreceiver can wake up and process the configuration files promptly when receiving SIGHUP. Because the standard SIGHUP handler sets the latch. On the other hand, previously there could be a time lag between the receipt of SIGHUP and the process of configuration files since the dedicated handler didn't set the latch.
