#6 SEG fault caused by initDeviceList

[Roland Moser]

When trying to access Devices cached by the
ControlPoint using e.g. getDeviceList(...), I often
get an SEG fault.

This is due to the Disposer Thread which
reinitializes all Devices in initDeviceList. In this
function every device in the old deviceList is
deleted and a new deviceList is generated. This is
also done, when the device was not removed from the
network. This behaviour leads to invalid Device
pointers, when:
1. retrieve a device pointer
2. disposer thread calls initDeviceList
3. device pointer is invalid and application seg
faults

A patch which only deletes "removed devices" and only
adds new "added devices" when necessary is attached.

splitting up the patches in smaller parts destroyed them
somehow :( - so here the correct one which applies with no
rejects

found an error an my patch - old devices will be deleted
when the deconstructor of the temporary list is called.
New Patch attached
