Change test_main to run a single test case out of the suite

Browse Source 
By passing the name of the test function on the command line
we execute exactly that one test, and then exit successfully
if the test did not fail.  This permits multiple functions in
the same .c file, so they could be called from a shell script
or debugged independently externally.
