[PATCH v1 00/34] Rework building of domain's namespaces

There are couple of things happening in this series. The first patch fixes a bug. We are leaking /dev/mapper/control in QEMU. See the patch for detailed info. The second patch then cleans up code a bit. The third patch moves namespace handling code into a separate file. Patches 4 - 15 then prepare the code for switch to different approach in populating the namespace. Patches 16 - 26 then do the switch and finally, the rest of the patches drops and deduplicates some code.
