Fix 1.7 tablist behaving weird with colored names 
The 1.7 tablist packet only contains three types of information:

 - Name of the tablist entry (limited to 16 characters including colors)
 - Ping of the entry
 - If this entry needs to be added or removed (client accepts duplicates
 as 'ping update')

The previous logic was trying to preserve parity with
GameProfile#getName returning a stripped down name to have a 'real'
username.
That is fundamentally broken, because entries with duplicate content,
but different colors are very common, especially with custom tablists.

For packets coming from a native 1.7 server we just won't define the
displayname anymore, as there is no such thing as a 'displayname',
because tablist entries are not bound to any player.

Using the Velocity Tablist API to modify existing entries will work, though
the backend server will completely loose control over the entry. Custom
entries added over the Velocity Tablist API will work, but are cut off
by the 16 character limitation.

This commit only fixes the bug, where entries are incorrectly handled
with their stripped name, a lot of the things explained above were
already implemented correctly.

Don't send ping update twice 
VelocityTabListEntry#setLatency calls the update method, which
constructs a new packet and sends it to the client.
The backend packet we are processing also reaches the client, therefore
we are sending the same packet twice.
VelocityTabListEntry#setLatencyInternal is the correct method here.

This is a niche setup, however if your network is 100% dynamically configured, this is a handy feature to have available.

010a10f50f Do not try to prevent people from running Velocity behind Velocity. 
This commit absolutely does not change our support policy on this: this
is a completely unsupported setup. In any event, there is an existing
forwarding check in Velocity that covers this case quite well.

I am making this change to make the login process less "chatty" for
higher-latency links and 1.13+ servers.

non-macOS and non-Linux platforms (such as Windows).

009c9afe09 Decode multiple VarInt-prefixed packets 
If the remote server does flush consolidation, Velocity will be able to
frame the packets all at once instead of having to constantly decode
packets. This should provide a modest performance boost for them whilst
not impacting un-optimized servers.

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.
