    ssp: fix our gets_s implementation under _FORTIFY_SOURCE

    Annex K specifies an interface for handling constraint violations from
    gets_s, but we previously broke this for some classes of get_s misuse.

    Provide a more nuanced version that tries to dodge errors that would
    trigger a constraint handler while still providing value.  Notably, we
    don't want to trigger a failure unless the passed-in length reasonably
    fits within an RSIZE_MAX, because gets_s will immediately call larger
    lengths bogus and fail.
