[PATCH] libnuma: maintain numa_num_thread_nodes() and numa_num_thread_cpus()

[Cliff Wickman <cpw@xxxxxxx>]

From: Cliff Wickman <cpw@xxxxxxx>
    
Maintain compatibility for codes using version 2.0.3 numa_num_thread_nodes()
and numa_num_thread_cpus().
The man page will only document the new names.

The qthreads package, for example, still calls the "thread" names.
