Norman Feske 83bdfea9b0 Extend Cpu_session with thread-affinity API
This patch introduces the functions 'affinity' and 'num_cpus' to the CPU
session interface. The interface extension will allow the assignment of
individual threads to CPUs. At this point, it is just a stub with no
actual platform support.
