sslutil: store flag for whether cert verification is disabled

This patch effectively moves the ui.insecureconnections check to
_hostsettings(). After this patch, validatesocket() no longer uses the
ui instance for anything except writing messages.

This patch also enables us to introduce a per-host config option
for disabling certificate verification.
