Subject: [PATCH] Always let the OS auto-tune the socket send/receive buffer
 size (#1821)

Remove the explicit SendBufferSize/ReceiveBufferSize assignment
from both SocketConnect and SocketConnectAsync. This lets the
operating system auto-tune the buffer for every connection by
default, and resolves the sync/async multiplier mismatch.
