Detect X server exit status instead of doing timeouts

[midenok]

There are 3 reasons why server exited:

1. Crash;
2. Configuration error;
3. User initiative (including Ctrl + Alt + Backspace).

Usually they are differentiated by exit code (it also includes signal which caused termination). That's what nodm must do correspondingly:

1. Restart and if crashed again in short timeout exit without further restarts;
2. Exit immediately;
3. Restart (without timeouts) or exit depending on configuration.

So timeout should be accounted only for crash and only one time (who needs X server crashing more frequently than working).

I just dropped @softlab a note via his nodm fork on Github. The nodm display manager is in deep need for another upstream maintainer. I pinged @softlab if he'd be willing to step up for this job. It needs someone who uses nodm on a regular basis and who encounters errors when they pop up.

Neither @spanezz nor myself (@sunweaver) are maintaining nodm actively anymore. I have also stopped using it (because I lack the customer use cases these days). But, still, I think that nodm fills a gap in the display manager universe.
