  Updated DBUG_PRINT
sql/mysqld.cc:
  Added that max_relay_log_size copies it's values from max_binlog_size
sql/mysqld.h:
  Removed max_relay_log_size
sql/rpl_mi.cc:
  Changed names of multi-source log files so that original suffixes are kept.
sql/rpl_mi.h:

  Updated comment to reflect new code
  Made max_relay_log_size depending on master connection.
sql/rpl_rli.h:
  Made max_relay_log_size depending on master connection.
sql/set_var.h:
  Made option global so that one can check and change min & max values (sorry Sergei)
sql/sql_class.h:
  Made max_relay_log_size depending on master connection.
sql/sql_repl.cc:
  Updated calls to create_signed_file_name()
