Refactoring: Moved rli code to new file rpl_rli.cc. The idea being that rli

should be a separate module (i.e. a class) to make it easier to maintain the 
code, e.g. by having checks within the rli checking sanity of data and making 
member variables private.  This will also ease implementation of multi-source 
and, at least in my fantasies :), make it possible in some future to have 
separate replication servers.


sql/Makefile.am:
  Added file rpl_rli.cc
sql/repl_failsafe.cc:
  Move function
sql/rpl_rli.h:
  moved functions
sql/slave.cc:
  Moved rli code into rpl_rli.cc
sql/sql_repl.cc:
  Changed function to be member function
sql/rpl_rli.cc:
  Code for rli

sql/rpl_rli.h
