Extended mysqlslap.c for auto tests (see the comment on the mysqlslap.c file)....

Extended mysqlslap.c for auto tests (see the comment on the mysqlslap.c file). I also fixed a bug where limit was not being reached. 


client/client_priv.h:
  More options
client/mysqlslap.c:
  Extended the auto-sql in the following ways:
  1) You can now specify a load type of either "mixed", "read", or "write". Not great, but a definite improvement.
  2) A new option allows you to specify how many rows are inserted for the "read" load. 
  
  I also fixed a bug where limit was not being reached by running threads.
