Improve demo/testing code in client/server2
Previously it was missing reset in case 1, and in case 2 the code was never executed as the option value was reset to 0. Tighten checking of return values of save(NULL, 0) now that it works. Also, improve the printed output as well as the comments. I checked manually that everything now works and fail in the expected way: save, reset-or-reinit and load all succeed, but the subsequent read or write fails.
