837e1a72a4 tcp_send_buffered.c: improve tcp write buffering 
* Send data chunk-by-chunk
  Note: A stream socket doesn't have atomicity requirement.

* Increase the chance to use full-sized segments

Benchmark numbers in my environment:

* Over ESP32 wifi
* The peer is NetBSD, which has traditional delayed ack TCP
* iperf uses 16384 bytes buffer

Urgent data preceded "normal" data in the TCP payload.  If the urgent data is larger than the size of the TCP payload, this indicates that the entire payload is urgent data and that urgent data continues in the next packet.

This case was handled correctly for the case where urgent data was present but was not being handled correctly in the case where the urgent data was NOT present.
