- Use max_state_alt in check_ntp to fix some issues with the latest commits.

- Roll back the stratum check as there were issues with it and a better one is already implemented in check_ntp_peer (about to be included)

 1.4.11 or 1.5 ??
        Fix check_http regression in 1.4.10 where following redirects to
          relative URLs on virtual hosts failed if both "-H" and "-I" were used
-       Add stratum thresholds support to check_ntp (feature request #1703823)
        check_ntp now return UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
          as long as the thresholds range inculde -1. If no offset threshold is specified
          and the offset is unavailable, will return UNKNOWN as well.
