121ab41d96 Introduce TCP_FASTOPEN support 
For best results, use Linux 4.11+ and a server modified to set the
TCP_FASTOPEN flag.

This should in particular benefit users of legacy forwarding.

d1736bf94c Move from custom HTTP client to Async HTTP Client 
The most significant advantage is that Velocity gets a well-tested
HTTP client implementation which also includes a connection pool,
allowing us to avoid the overhead of TCP and TLS handshakes upon each
login.

Unfortunately, Async HTTP Client does not work with the kqueue transport.
Since almost nobody runs a production Velocity server on macOS, we have
decided to remove kqueue support. The benefits that Async HTTP Client
provides outweigh the disadvantages of not having a macOS native transport.
macOS is adequately supported by the normal NIO transport.

fde5ec36e7 Update TerminalConsoleAppender to 1.2.0 
Add log4j.skipJansi to prevent Log4j from initializing a Jansi
terminal. It is redundant because this is handled by TCA and it
will be only active for a few seconds until TCA is loaded.

df9883cc6c Reduce unnecessary memory copies in StatusSessionHandler 
Take advantage of the fact that Java has mutable strings when writing
out server ping responses, which Netty can work with when writing out
UTF-8 character sequences. This reduces the memory allocation impact of
server list ping responses by ~31%.

9e6e1856e6 Add /glist command. 
A much-needed base command, this is now available in Velocity directly.
It is partially inspired by the RedisBungee /glist command, which I also
created.

By default, /glist only provides the player count of the proxy. You can
view the player list for an individual server with /glist <server>, or
you can view the information for all players with /glist all.

An Easter basket bearing gifts! (#191) 
* Delay switch to new server until after JoinGame is sent.

Unfortunately, in some cases (especially vanilla Minecraft) some login
disconnects are sent after ServerLoginSuccess but before JoinGame.
We've been using ServerLoginSuccess but it has caused too many problems.
Now Velocity will switch to a stripped-down version of the play session
handler until JoinGame is received. This handler does very little by
itself: it simply forwards plugin messages (for Forge) and waits for the
JoinGame packet from the server.

This is an initial version: only vanilla Minecraft 1.12.2 was tested.
However this is the way Waterfall without entity rewriting does server
switches (which, in turn, is inherited from BungeeCord).

* Move to Gradle 5 and Error Prone.

Fix implementation of #176 
As @creeper123123321 noted on Discord, the javadoc specifies "Matches all {@link Player}s whose names start with the provided partial name.".

With the current implementation, if there were two online players named Notch and Notch2, only Notch would be returned as a singleton Collection. This PR fixes this behavior by removing the `exactMatch` code.

5dbe6aa808 Rename connection field in ConnectedPlayer. 
This sounds stupid, but YourKit really casts its net wide when it tries
to instrument usages of JDBC. Velocity doesn't use JDBC, and yet if you
run Velocity with YourKit (even without profiling active) you pay a
significant cost.

8588e7f1fe Optimize native handling further. 
We now try to work within the boundaries given by the native. In the
case of Java natives, we work with byte arrays. With natives, always use
direct buffers.

However, the numbers do favor the natives, since they work with direct
byte buffers, without any copying. For the most part, this commit is
intended to improve the lives of Velocity users on Windows.

ccd37e5b9c Track the forge handshake and re-engineer Forge support 
The system is now organised into connection types and phases. Most of the core Velocity logic is now isolated from the Forge logic to allow for simpler maintainance and to try to support future loaders (Forge 1.13?) in a cleaner fashion.

There are a couple of points where Forge specific calls are in the main body, but these have been minimised.

Also send keepalives from Velocity to during backend server switch and after Forge handshake, to try to help Forge clients

070631902a Fix some suboptimal behavior in invoking KickedFromServerEvent. 
Previously, the event would only fire when a player was kicked from the
current server they were on. Now, under certain cases, it can be fired
even if the player was already connected to a server.

To faciliate this, a new result (Notify) was introduced. This result
will "do the right thing" if the player is kicked from the current
server or is trying to connect to a different server than the one they
were on.
