Summary:
    Registers Fifo that is used to log debug data

Description:
    When this function is called and fifo is not NULL, then debug output instead
    of being routed to the debug console, is stored in the provided FIFO.
    THen application could use BDBG_Dequeue_Fifo to extract and print messages 
    logged into FIFO. 
    If FIFO is NULL debug output then directed to the debug console .

Note:
    Element size of the provided FIFO should match number retuirned buy
    BDBG_Log_GetElementSize

See Also:
    BDBG_Log_Dequeue
    BDBG_Fifo_Create
    BDBG_Log_GetElementSize

Example:
    #include "bstd.h"
    BDBG_MODULE(some_module)

Input:
    <none>

Returns:
    <none>
