Update of bug #52554 (project lwip):

                  Status:                    None => Fixed                  
             Open/Closed:                    Open => Closed                 


Follow-up Comment #1:

Should be fixed:
- netconn is not freed from lwip_close() directly but freeing it is delayed
until fd_used gets 0
- shutdown and close don't drain the mbox in fullduplex mode but post a
message that wakes up waiting threads and tell them the netconn is about to be
deleted. Draining is done when the netconn is actually deleted
