    time: eliminate deltaless_tv_dt(), use deltatime_cmp()

commit 6789baf9f41136f1be01393cd8ce10bfd2100f74

    time: improvise on timercmp(A,B,CMP) defining deltatime_cmp(A,CMP,B)
    
    For instance deltatime_cmp(A, <, B).  Subjectively less ugly than
    deltatime_cmp(A, B) < 0, and more readable than deltaless(A,B).
