vdr-shutdown changes

[Tobias Grimm]

Hi!

I would like to solve some small issues with vdr-shutdown:

1) The problem: vdr-shutdown always executes all shutdown hooks to find 
the maximum shutdown delay a hook may request. This causes the 
nvram-wakeup-hook to be executed, even if the shutdown will be delayed. 
The next time nvram-wakeup is called during the real shutdown, it will 
see that the right time is already set and won't request a reboot, if 
the board requires this.

Calculating the maximum shutdown delay is IMHO not really necessary. I 
think it would be ok, that after the first shutdown hook that requests a 
delay, no further hooks will be executed. This way nvram-wakeup, which 
should be the last hook, is only executed when the system really shuts down.

2) Currently a shutdown is always done by the commands "/etc/init.d/vdr 
stop ; sleep 1 ; /sbin/shutdown -h now". I think this should be 
configurable in /etc/default/vdr (SHUTDOWNCMD="whatever").

Any objections? If not, I will change this in 1.2.6-6.

bye,

Tobias
