* bgpd/bgp_dump.{c,h}: (bgp_dump_interval_add) Dump at discrete
          fixed intervals rather than fixed intervals from startup time.
          (bgp_dump_interval_func) Dont return immediately if file cant be
          openeded, but reschedule interval dumps, even - admin might
          fix problem in meantime. Close the dump file in between intervals.
          (bgp_dump_init) account for MSG header when initialising stream
	  size.
