821ca02ee7 Backport Velocity Polymer's async event API, with changes. 
This commit backports the event manager from Velocity Polymer, with some changes for Velocity 1.1.x API compatibility:

- All event handlers run asynchronously. (While EventTask.async() exists, it is not useful in 3.0.0, but is provided as a migration aid for Polymer.)
- Event ordering is currently limited to the 5 levels available in Velocity 1.x.x.

1cef82d54d Unroll the VarInt writing loop 
This is about as optimized as it can get. Thanks to @Leymooo for the idea, I simply expanded on it. We optimize for the common 1-3 byte cases, and punt more "complicated" cases to the original VarInt writing function we had before.

4ca97a6df9 Reapply "Optimize varint writing" 
Inspired by the approach described at the bottom of https://richardstartin.github.io/posts/dont-use-protobuf-for-telemetry

Given that we do a lot of varint writing as well, this should provide a small performance boost for larger/complex packets whilst not regressing hard on smaller packets.

This includes a test to ensure that the behavior is as expected and fixes the initialization loop so that the correct results will be given. Much thanks to @octylFractal for acting as my duck while trying to figure this out.

f1cb3eb1a2 Move timeout handler to after frame decoder

7a713e9379 Update bStats and migrate to new config file 
This commit simplifies the Metrics class by using the new base module
from bStats. It also migrates to the new bStats config file that will
be used by plugins that integrate bStats. If a user disabled bStats in
the old config file, this setting will be copied to the new config file.
