netclientclock patch for round-trip limiting

The netclientclock currently assumes that the network is of good quality, does
not delay the packets too much, transports them in order etc. These assumptions
generally hold for wired local networks, but not for wireless ones. In an area
with many Wi-Fi access points and clients, time packets with round trips of 10
seconds have been observed. These extremely late packets mess up the regression
calculations, causing the clock's stability to degrade significantly.

This patch introduces a limit for the round trip period. If a packet takes
longer to return than the limit specifies, it is ignored. By default, the limit
is set to zero, which disables the limiting. (It is very difficult to determine
a "good"
nonzero default value.)
