configure.py: import traceback to be available in all necessary branches

Add more code for printing tracebacks on various failures

Have C,C++, and Fortran attempt to print versions as soon as the compiler is detected

Change ERROR in COMMAND LINE ARGUMENT to ./configure

Add more code for printing tracebacks on various failures

Have C,C++, and Fortran attempt to print versions as soon as the compiler is detected

Change ERROR in COMMAND LINE ARGUMENT to ./configure message to TypeError or ValueError possibly related to ERROR in COMMAND LINE ARGUMENT to ./configure to prevent confusion with the earlier ERROR in COMMAND LINE ARGUMENT message
and to clarify that it may not be related to command line arguments

include <stdio.h> in dynamic library test to remove warnings from compiler about missing includes when
printf is used
