Add loop.c -- a test program for repeatedly calling Py_Initialize()

and Py_Finalize().  It seems to dump core right now...

+An additional test program, loop.c, is used to experiment with memory
+leakage caused by repeated initialization and finalization of the
+interpreter.  It can be build by saying "make loop" and tested with
+"make looptest".  Command line usage is "./loop <python-command>",
+e.g. "./loop 'print 2+2'" should spit out an endless number of lines
+containing the number 4.
