Gregory Nutt cf5cba953d There was a possible recursion that could eventually overflow the stack. The error occurred when closing the socket with inet_close() while a socket callback was still queued. When the socket callback was executed by devif_conn_event(), this resulted in a call to psock_send_eventhandler() with TCP_CLOSE flag set which then called tcp_lost_connection(). tcp_shutdown_monitor() then called tcp_callback() again, which again called psock_send_eventhandler(), and so on.... Noted by Pascal Speck. Solution is also similar to a solution proposed by Pascal Speck.

Networking: Fix a race condition. The accept() operation is performed with the network locked. However, the network is unlocked BEFORE the connected state is set. Therefore, a context switch may occur and the socket may no longer be connected when it is marked so. Noted by Pascal Speck.
