CraftBukkit removed their implementation that caused this issue,
switching to Mojang's implementation which doesn't appear to share it. I
already removed the important bit in the last upstream merge, this is
just unused and unnecessary now. So we remove it.
We have long been receiving feedback about our warning messages when
excessive velocities are set on entities. We have, for the most part,
ignored much of this feedback because these warnings can be vital in
identifying the cause of a watchdog crash. These crashes would otherwise
be more difficult to identify without this information.
However, in many cases these warnings are unnecessarily verbose as the
server handles these excessive sets itself without user intervention.
As a compromise, we will only warn the user as part of a watchdog crash
log, and we will only include the most recent occurrence. This commit
represents a first effort on this front. It may need to be tweaked later
to provide more relevant information, such as the time it occurred,
and/or not printing the warning at all if the occurrence was a certain
time period ago.
