#6 find # CPUs automatically

[Dimitri Papadopoulos]

The number of CPUs on a host could be found
automatically by loadavg and sent to the dmucs server
instead of specifying that in a config file.

I think there is already code to find the number of
CPUs in the distcc sources. If not, see for example:
