    PPP, PPPoS, fixed thread safety of pppos_input()
    
    PPPoS was actually not thread safe, pppos_input() can be called from
    lwIP user port at any time, whatever the PPP state is. It might even be
    called during pppos_connect() and pppos_listen(), this is quite unlikely
    the port do that but nothing prevent the user to since we document
    pppos_input() as being thread safe.
    
    Added a mutex if PPP_INPROC_MULTITHREADED is set and ensure pppos_input()
    is safe in regard to other pppos_* functions.
