libxl / LXC / QEMU drivers share some common codes in their
DomainDetachDeviceConfig functions, so extract them to domain_conf and
use them with xmlopt etc to deduplicate the bigger function.
At the same time, this will enable test driver to test these functions
in the future.

Compare to the v3, I remove the random comments, and align the
error messages, also add virDomainDetachChrDeviceConfig by using xmlopt. Then
I got a lot of choices here:
1. Just cleanup these functions and using them in drivers, just like what I did
in the previous patch.
2. Add a bigger de-duplicated function to de-duplicate the function in libxl /
LXC / QEMU drivers, and this is what I choose in this patch.
3. Merge all the functions into the bigger one, instead of splitting them
This would still de-duplicate the functions in libxl / LXC / QEMU drivers.
I choose the second here as I think there would be a situation that both
these single device detach functions and the bigger function would be used
in drivers.
