[TIPC]: Optimize stream send routine to avoid fragmentation
This patch enhances TIPC's stream socket send routine so that it avoids transmitting data in chunks that require fragmentation and reassembly, thereby improving performance at both the sending and receiving ends of the connection. The "maximum packet size" hint that records MTU info allows the socket to decide how big a chunk it should send; in the event that the hint has become stale, fragmentation may still occur, but the data will be passed correctly and the hint will be updated in time for the following send. Note: The 66060 byte pseudo-MTU used for intra-node connections requires the send routine to perform an additional check to ensure it does not exceed TIPC"s limit of 66000 bytes of user data per chunk.
