Reported in #1561470 (http://curl.haxx.se/bug/view.cgi?id=1561470), libcurl

would crash if a bad function sequence was used when shutting down after
using the multi interface (i.e using easy_cleanup after multi_cleanup) so
precautions have been added to make sure it doesn't any more - test case 529
was added to verify.
