Subject: [PATCH] Limit Client Sign length more
modified clients can send more data from the client
to the server and it would get stored on the sign as sent.
Mojang has a limit of 384 which is much higher than reasonable.
the client can barely render around 16 characters as-is, but formatting
codes can get it to be more than 16 actual length.
Set a limit of 80 which should give an average of 16 characters 2
sets of legacy formatting codes which should be plenty for all uses.
This does not strip any existing data from the NBT as plugins
may use this for storing data out of the rendered area.
it only impacts data sent from the client.
Set -DPaper.maxSignLength=XX to change limit or -1 to disable

Subject: [PATCH] Optimize Network Manager and add advanced packet support
Adds ability for 1 packet to bundle other packets to follow it
Adds ability for a packet to delay sending more packets until a state is ready.
Removes synchronization from sending packets
Removes processing packet queue off of main thread
- for the few cases where it is allowed, order is not necessary nor
should it even be happening concurrently in first place (handshaking/login/status)
Ensures packets sent asynchronously are dispatched on main thread
This helps ensure safety for ProtocolLib as packet listeners
are commonly accessing world state. This will allow you to schedule
a packet to be sent async, but itll be dispatched sync for packet
listeners to process.
This should solve some deadlock risks
Also adds Netty Channel Flush Consolidation to reduce the amount of flushing
Also avoids spamming closed channel exception by rechecking closed state in dispatch
and then catch exceptions and close if they fire.
