Make GTlsInteraction virtual methods cancellable

* Add cancellable argument to g_tls_interaction_ask_password
   and g_tls_interaction_ask_password_async.
 * This is API breakage, but this API has not yet been released
   in a stable release (and very unlikely used yet).
 * Since we're breaking unreleased API, expand amount of padding
   on GTlsInteractionClass because we're going to need it.
