Here comes a nasty patch, although I am not ready to push it yet. I will

Browse Source 
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.

include/my_sys.h:
  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.
