another DeviceKit backend for Solid

[Benjamin K. Stuhl]

(resending, since I wasn't subscribed to fedora-kde; my apologies if you get 
duplicates...)

Folks,
  I committed another, alternative, DeviceKit-based Solid backend to KDE's 
Subversion repository yesterday, in branches/work/alternative-solid-devicekit. 
It grew out of some experiments I was doing with writing a Qt-ish libudev 
wrapper (you can see the API in solid/backends/udevqt.h). Since it got large 
enough to perhaps be useful to other people, and also to convince me that the 
general approach would work, I imported it into Subversion from my GitHub 
repository. The major difference from Pino and Lukas's work/solid-devicekit 
branch is that I also use libudev for enumeration, as well as DeviceKit-*; I 
have also made an effort to try to minimize the amount of boilerplate code each 
Interface needs (c.f. solid/backends/devicekit/dkdevice.cpp:dbusDeviceCall() 
and solid/backends/devicekit/dkinterface.h). Please take a look and comment or 
help out, especially if you know DeviceKit or libudev.
  Pino, Lukas: I wasn't particularly trying to rewrite all your code, so I'm 
SVN-copying your DeviceKit-disks-based parts from your work/solid-devicekit 
branch and modifying them to fit in. I'd be happy if you would like to 
contribute, but if you like your original design better and want to keep 
working on it, I understand that too. One question: the code I wrote is 
LGPLv2+, while your code is LGPLv2-only. If you do like my branch, would you 
be willing to relicense your code to LGPLv2+ for consistency?
