DOC: stconn: Update comments about ABRT/SHUT for stconn structure
The comment for the stconn structure was still referencing the SHUTR/SHUTW
flags. These flags were replaced and we now use ABRT/SHUT flags in
comments. The comment itself was slightly updated to be accurate.

- * a shutw() when it has consumed the last contents, otherwise the session processor
- * will do it anyway.

- * The SHUT* flags work like this :
+ * The SC_FL_SHUT_WANTED flaga should be set by the session processor when
+ * SC_FLABRT_DONE/SC_FL_EOS and CF_AUTO_CLOSE are both set. And it may also be
+ * set by the producer when it detects SC_FL_EOS while directly forwarding data to the
+ * consumer.
*
- * SHUTR SHUTR_NOW meaning
- * 0 0 normal case, connection still open and data is being read
- * 0 1 closing : the producer cannot feed data anymore but can close
- * 1 0 closed: the producer has closed its input channel.

- * SHUTW SHUTW_NOW meaning
