    various: Fix always-true/false address comparisons (-Waddress).
    
    GCC 15 warns when comparing the address of a struct member against
    NULL, since such addresses can never be NULL. Replace with emptiness
    checks where intent was "is it set", remove dead guards otherwise.
    
    Also fixes a latent bug in telnet ring.c where a pointer expression
    was used as a boolean instead of as the RHS of a comparison.
