Updated Upstream (Bukkit/CraftBukkit)
Upstream has released updates that appears to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing

My recent work on serialization is now in CraftBukkit so was able to drop the patch and Paper
is now consistent with upstream.

Subject: [PATCH] Sync position on teleportation
We've seen many a cases where the "last good" x/y/z is desynced from
the x/y/z that is checked for moving too fast.
Theory is that when you have multiple movement packets queued up,
and the player is teleported after the first then the 2nd and 3rd come in,
it is triggering a massive movement velocity.
This will ensure that the servers position is synchronized anytime player is teleported.
