Fix some more bugs in signal handlers and process shutdown logic. WalSndKill was doing things exactly backwards: it should first clear MyWalSnd (to stop signal handlers from touching MyWalSnd->latch), then disown the latch, and only then mark the WalSnd struct unused by clearing its pid field.
Also, WalRcvSigUsr1Handler and worker_spi_sighup failed to preserve errno, which is surely a requirement for any signal handler. Per discussion of recent buildfarm failures. Back-patch as far as the relevant code exists.
