slapd/syncrepl.c dumps core in strcmp()

 because *uuid1 == *uuid2 == (struct berval) { 0, NULL }
 when called from syncuuid_cmp(),

 called from avl_insert() in syncrepl_entry(),
 called from do_syncrepl() with syncUUID == (struct berval) { 0, NULL }.

Which means that null bervals are both in the argument to avl_insert
and in the tree.
