Library: topology query (node awareness)

[GoogleCodeExporter]

I think we forgot to add an issue for this ongoing discussion:

ibrary-extensions/node-awareness

The basic idea is to add library support for querying information about a 
thread's "distance" to selected blocks of shared memory, to enable application 
performance tuning for topology on systems with non-uniform hierarchical memory 
layouts (ie virtually all production HPC systems).

All "brand new" library proposals are targeted for starting in the "Optional" 
library document. Promotion to the "Required" document comes later after at 
least 6 months residence in the ratified Optional document, and other 
conditions described in the Appendix A spec process.
