Update to version 3.78

Changes:

- The XML nmaprun element now has a startstr attribute which gives the
  human readable calendar time format that a scan started.  Similarly
  the finished element now has a timestr attribute describing when the
  scan finished.  These are in addition to the existing nmaprun/start
  and finished/time attributes that provided the start and finish time
  in UNIX time_t notation.  This should help in development of better
  XSLT stylesheets for Nmap XML output.

- Added new "closed|filtered" state.  This is used for Idlescan, since
  that scan method can't distinguish between those two staes.  Nmap
  previously just used "closed", but this is more accurate.

- Rewrote the host IP (target specification) parser for easier
  maintenance and to fix a bug found by Netris (netris(a)ok.kz)

- Fixed compilation on soem HP-UX 11 boxes thanks to a patch by Petter
  Reinholdtsen (pere(a)hungry.com).

- Fixed a portability problem on some OpenBSD and FreeBSD machines
  thanks to a patch by Okan Demirmen (okan(a)demirmen.com).

- Added an NTP probe and matches to the version detection database
  (nmap-service-probes) thanks to a submission from Martin Macok
  (martin.macok@underground.cz).
