Re: [libvirt] PATCH: Centralize some duplicated NUMA code

The QEMU and UML drivers currently duplicate a non-trivial chunk of NUMA code. This patch moves it all into src/nodeinfo.c which already has some other common NUMA code for capabilities initialization. In doing so it changes the functions to have a common 'nodeXXXX' naming scheme, to avoid clash with the public APIs using 'virXXXX'. Finally, these central functions can be directly used in the driver function tables, so we kill off some pointless wrappers and just add these funtions directly to drivers.
