isdn: fix information leak The main motivation of this patch changing strcpy() to strlcpy(). We strcpy() to copy a 48 byte buffers into a 49 byte buffers. So at best the last byte has leaked information, or maybe there is an overflow? Anyway, this patch closes the information leaks by zeroing the memory and the calls to strlcpy() prevent overflows.
