* (general) SPF millisecond resolution timer with adaptive, linear back-off holdtime. Prettification of ospf_timer_dump. * ospf_dump.c: (ospf_timeval_dump) new function. The guts of ospf_timer_dump, but made to be more dynamic in printing out the relative timeval, sliding the precision printed out according to the value. (ospf_timer_dump) guts moved to ospf_timeval_dump. * ospf_dump.h: export ospf_timeval_dump. * ospf_flood.c: (ospf_flood) remove gettimeofday, use the libzebra exported recent_time instead, as it's not terribly critical to have time exactly right - the dropped LSA will be retransmited to us if we don't ACK it. * ospf_packet.c: (ospf_ls_upd_timer) Ditto, but here we're not transmitting, just putting LSA back on update transmit list. * ospfd.h: delay and holdtimes should be unsigned. Add spf_max_holdtime and spf_hold_multiplier. Update default defines for delay and hold time to be in msec. (struct ospf) change the SPF timestamp to a struct timeval. Remove ospf_timers_spf_(un)?set. * ospfd.c: (ospf_timers_spf_{set,unset}) removed. (ospf_new) initialise spf_max_holdtime and spf_hold_multiplier * ospf_spf.c: (ospf_spf_calculate) SPF timestamp is a timeval now, update with gettimeofday. (ospf_spf_calculate_schedule) Change SPF timers to millisecond resolution. Make the holdtime be adaptive, with a linear increase in holdtime ever consecutive SPF run which occurs within holdtime of previous SPF, bounded by spf_max_holdtime. * ospf_vty.c: Update spf timers commands. (ospf_timers_spf_set) trivial helper. (ospf_timers_throttle_spf_cmd) new command to set SPF delay, initial hold and max hold times with millisecond resolution. (ospf_timers_spf_cmd) Deprecated. Accept the old values, convert to msec, truncate to new limits. (no_ospf_timers_throttle_spf_cmd) set timers to defaults. (no_ospf_timers_spf_cmd) deprecated form, same as previous. (show_ip_ospf_cmd) Display SPF parameters and times. (show_ip_ospf_neighbour_header) Centralise the 'sh ip os ne' header. (show_ip_ospf_neighbor_sub) Fix the field widths. Get rid of the multiple spaces which were making the lines even longer. (show_ip_ospf_neighbor_cmd) Use show_ip_ospf_neighbour_header (show_ip_ospf_neighbor_all_cmd) ditto and fix the field widths for NBMA neighbours. (show_ip_ospf_neighbor_int) Use header function. (show_ip_ospf_nbr_nbma_detail_sub) use sizeof for timebuf, local array - safer. (show_ip_ospf_neighbor_detail_sub) ditto (ospf_vty_init) install the new SPF throttle timer commands.

* (general) OSPF fast, sub-second hello and 1s dead-interval
support.
* ospf_dump.c: (ospf_timer_dump) Print out milliseconds too.
