The patch adds _Xil8n_lock mutex for lcd_list access in _XCloseLC() and it also
creates a new mutex _conv_lock for conv_list access in locking.c which is used
in converter functions in lcConv.c.

I don't know why after all these years this bug is still open and is this patch
a thing which will solve all the problems but at least in my case I was able to
get rid of lock ups and crashes when running SierraChart on Wine. The same has
happened for many others in SierraChart message board.

So while waiting better solutions/patches I am just using it and happy.
