commit d4738e1259f97ee14687300ee01e6e6da4701bb4

    ntp: set minimum polltarget
    
    The polltarget value is used in a floating-point division in the
    calculation of the poll adjustment. Set 1 as the minimum accepted
    polltarget value to avoid working with infinite values.

    ntp: reset polling interval when replacing sources
    
    Set the polling interval to minpoll when changing address of a source,
    but only if it is reachable to avoid increasing load on server or
    network in case that is the reason for the source being unreachable.
    
    This shortens the time needed to replace a falseticker or
    unsynchronized source with a selectable source.

    ntp: avoid unneccessary replacements on refresh command
    
    When the refresh command is issued, instead of trying to replace all
    NTP sources as if they were unreachable or falsetickers, keep using the
    current address if it is still returned by the resolver for the name.
    This avoids unnecessary loss of measurements and switching to
    potentially unreachable addresses.
