Zbigniew Jędrzejewski-Szmek 66f737b415 udev: do not pass timeout_warn_usec around, calculate it on demand 
It was always set to one third of timeout_usec, so let's simplify things by
calculating it using a helper function right before it is used.

Before 9d9264ba39, udevd.c would avoid setting
timeout_warn_usec to 0, using 1 instead. This wasn't necessary, because when
timeout_warn_usec is finally used in spawn_wait(), it is ignored if
timeout_usec is 0 or timeout_warn_usec is 0. So there was no need to handle
this case specially.

Yu Watanabe d4a95a952e udev-event: check whether device has devnum before calling udev_node_remove()

not be initialized.

For some reason they were missed previously. All those files seem to
have proper SDPX tags.

Lennart Poettering 4c253ed1ca tree-wide: introduce new safe_fork() helper and port everything over 
This adds a new safe_fork() wrapper around fork() and makes use of it
everywhere. The new wrapper does a couple of things we previously did
manually and separately in a safer, more correct and automatic way:

1. Optionally resets signal handlers/mask in the child

2. Sets a name on all processes we fork off right after forking off (and
   the patch assigns useful names for all processes we fork off now,
   following a systematic naming scheme: always enclosed in () – in order
   to indicate that these are not proper, exec()ed processes, but only
   forked off children, and if the process is long-running with only our
   own code, without execve()'ing something else, it gets am "sd-" prefix.)

3. Optionally closes all file descriptors in the child

4. Optionally sets a PR_SET_DEATHSIG to SIGTERM in the child, in a safe
   way so that the parent dying before this happens being handled
   safely.

5. Optionally reopens the logs

6. Optionally connects stdin/stdout/stderr to /dev/null

7. Debug logs about the forked off processes.
