Problem: The include file "rpl_assert.inc" was added in 
         mysql-5.6. There exists another include file 
         "assert.inc" that dose the same and is more
         powerful. 
         "rpl_assert.inc" is an older version of
         assert.inc. Two major things have changed:
         1. assert.inc supports [COMMAND] for commands
            that return a single-row single-column result
            set
         2. assert.inc uses eval.inc, so code is better
            separated and more reusable. 

Fix: Replaced all usage of "rpl_asert.inc" by "assert.inc".
