[Qemu-trivial] [PATCH 0/4] cleanup -daemonize and pidfile creation a bit

[Michael Tokarev]

The $subject theme is quite messy, with many things done in a cryptic
and twisty way without any need for that.  This trivial patch series
tries to clean up and improve it.  In particular, it aims to make
pidfile errors visible with -daemonize -- something which Gonglei
tried to fix in e5048d15ce6a and which we're revering because that
fix turned out to be incomplete and wrong.

The patches are simple but I split them into several to easy review.

Michael Tokarev (4):
  os-posix: use global daemon_pipe instead of cryptic fds[1]
  os-posix: replace goto again with a proper loop
  pidfile: stop making pidfile error a special case
  os-posix: reorder parent notification for -daemonize
