* Fix comment documenting WorldSocket
The buffer is constructed with 4096 bytes but later resized in
WorldSocketThread::SocketAdded() according to the configuration
setting Network.OutUBuff (currently 65536 bytes)
* Reuse calculated packet size
Instead of recalculating the current packet size three times at
worst, calculate it once and reuse it when required.
* Reduce reserved buffer size per WorldSocket
Don't reserve 64kB of memory for every WorldSocket's output
buffer.
Instead, start with a 4kB baseline for every WorldSocket and grow
the buffer size dynamically when we have single packets that do
not fit the current buffer.
