    Improve the socket stress test to better test fullduplex

commit 3abc8ae1612878ea35b3c0a50ced55d867528dfc
Author: goldsimon <address@hidden>
Date:   Wed Apr 18 21:51:34 2018 +0200

    LWIP_NETCONN_FULLDUPLEX: unblock rx threads on close
    
    Threads blocked on the rx mbox are counted and on close,
    one "netconn closed" message per thread is posted to the mbox
    to ensure all threads are woken.
    
    The netconn can then be safely deleted. In socket API, "fd_used"
    and "fd_free_pending" help with auto-deleting the netconn.

commit 41fea4ad7dc68c844083883aac229576f46f3106
Author: goldsimon <address@hidden>
Date:   Thu Apr 12 17:19:30 2018 +0200

    sockets: change closing: netconn is freed when socket is closed, not before
    
    This is necessary to implement fullduplex sockets that are closed 
asynchronously:
    the netconn in the socket must not be freed before all threads have given up
    using it.
    
    We now call the first part of 'netconn_delete()' (moved to 
'netconn_prepare_delete()')
    from lwip_close() and only actually end up calling 'netconn_free()' from
    'free_socket()', which might be called later if LWIP_NETCONN_FULLDUPLEX is 
enabled.

commit 1090e9cdecd7ccf033293ec60212f3b1713d0b59

    LWIP_NETCONN_FULLDUPLEX: prevent taking recursive sys arch lock
    
    Calling SYS_ARCH_PROTECT() could happen twice in 'free_socket()' if
    that free was executed delayed (e.g. in 'done_socket_locked()').
