Fko dump

Hi Michael,

What do you think about those changes?

 * a dump_ctx_to_buffer() function in fko_utils.c that dumps the FKO context to a buffer.

I think the function cannot dump the context using the log_msg functions since it depends whether we are working with the server or the client. This way, each program uses its own implementation of message logging.

The server did not print the SPA packet before, but now it does. Do you think it could be a problem and the SPA message should be displayed separately?

Regards,
