    first pull, merge,test, and get it to work.
    
    The main change is the new replication code - now we have two slave threads
    SQL thread and I/O thread. I have also re-written a lot of the code to 
    prepare for multi-master implementation. 
    
    I also documented IO_CACHE quite extensively and to some extend, THD class.

      fixes in IO_CACHE for SEQ_READ_APPEND + some documentation
    libmysqld/lib_sql.cc:
      updated replication locks, but now I see I did it wrong and it won't compile. Will fix
      before the push.
