    Use va_copy() to get a copy of va_list, instead of using original.
    
    netsec_vprintf() can call vsnprintf() twice if the outgoing buffer is
    full (but it happens rarely in practice, given the way the current
    code uses it).  But if this DOES happen, vsnprintf() will use the
    same va_list argument twice, and the second time around either it will
    grab a random bit of memory off of the stack OR it will segfault.
    So we always use va_copy() to get our own copy of the passed-in va_list
    and work on that.
    
    (cherry picked from commit b47b562525f149f175c3d216feea20a6db2e9ff5)
