* Fix a crash in the S/MIME configuration screen when a user turned off S/MIME,
and then reenabled it. This crash was due to a double free of memory. To avoid this in the future, we created a function free_x509_store(), which whenever called, will only free memory once. A similar crash would occur when one attempted to enter the S/MIME configuration screen if S/MIME was turned off. In this case, Alpine would try to dereference a null pointer.
