buffer_getline - read line from buffer

       buffer_getline copies data from b to x[0], x[1], ..., x[len-1] until len bytes have been copied or a new-
       line character ('\n') is encountered.  That character is also copied.

       Note that line is not 0-terminated to make reading lines with 0-bytes possible through this interface.
