Let plugin_dispatch_values() set value_list.time in case of 'now'.

list. This is now done by plugin_dispatch_values() in case the time is zero

'struct timespec') as well. Also, it may now be NULL, in which case the
difference is not returned. This is a more general and thus more flexible
approach that permitted to remove the custom timeval_sub*() implementations in
the multimeter and ntpd plugins.

The return value has been changed to reflect the return value used by
functions like strcmp(), i.e. it is less than, equal to, or greater than zero
if the first argument is less than, equal to, or greater than the second
argument respectively.
