goldsimon b1b6275110 socket/netconn recv: FIN should only be reported once ... FIN should only be reported once (as '0' for sockets, as 'ERR_CLSD' for netconns). Before this change, ERR_CLSD was returned forever... This is the 2nd try. First try (commit ebcae98ae6) was buggy in that it could drop the FIN if it was read together with data (reverted in commit ebcae98ae6). This version fixes this by adding an apiflag and a netconn flag to keep track of this.		2018-02-04 20:16:53 +01:00
