util: Cleanup and rename os_mem_prealloc()

Browse Source 
Let's
* give the function a "qemu_*" style name
* make sure the parameters in the implementation match the prototype
* rename smp_cpus to max_threads, which makes the semantics of that
  parameter clearer

... and add a function documentation.
