    dhclient - Remove cur_time global.
    
    - Junk global cur_time, and use time(NULL) or local variables where
      time is checked multiple times. Add a set_timeout_interval() function
      to allow setting a timeout based on an interval from current time.
    
    - Fixes issues with initial startup where the global cur_time was
      always old and caused initial DHCPDISCOVER or DHCPREQUEST packets
      to be sent multiple times. And probably other timeout related
      oddities.
