nodeinfo: Fix gathering of nodeinfo data structure
This patch changes the way data to fill the nodeinfo structure are gathered. We've gathere the test data by iterating processors an sockets separately from nodes. The reported data was based solely on information about core id. Problems arise when eg cores in mulit-processor machines don't have same id's on both processors or maybe one physical processor contains more NUMA nodes. This patch changes the approach how we detect processors and nodes. Now we start at enumerating nodes and for each node processors, sockets and threads are enumerated separately. This approach provides acurate data that comply to docs about the nodeinfo structure. This also enables to get rid of hacks: see commits 10d9038b, ac9dd4a6. (Those changes in nodeinfo.c are efectively reverted by this patch). This patch also changes output of one of the tests, as the processor topology is now acquired more precisely.
