Restructured text is the kernel documentation format of choice now.
Some text from tcp.txt is out of date, specifically the function
tcp_write() does not appear to be in the tree anymore.  Also the
following data members have been removed

	  sk->tcp_pend_event
	  sk->transmit_queue
	  sk->transmit_new
	  sk->transmit_end
	  sk->tcp_last_tx_ack
	  sk->tcp_dup_ack

Remove section 'How the new TCP output machine [nyi] works'.  This
leaves only a single section so we can name the document with that
section heading now.

Convert tcp.txt to RST format.  Add GPLv2 SPDX tag.

I dunno, this 'doc' is probably useless and should be deleted.
