Add module ProcessorCount.cmake (#11302) Credit goes to David Cole ( http://www.kitware.com/blog/home/post/63 ). Also add a script-based test of the new module. Signed-off-by: Michael Wild <themiwi@users.sourceforge.net>

ProcessorCount: Use ERROR_QUIET with execute_process (#11302) Also, comment out all "debugging" calls to message() that helped us interpret the output on other platforms when running on the dashboard clients. Using ERROR_QUIET avoids unnecessary stderr output while calling external tools to determine the processor count. If there's an error parsing the output, we set the count to 0 anyhow. Also, the test will fail on a CMake dashboard run if the count comes back equal to 0. Now that the code is "done"-ish, remove the debugging output. Expect no output on stdout or stderr when calling the ProcessorCount function from now on.
