Bug #80	Obscure error message in replication (Error updating slave list: Query error)

Version:	4.0	OS:	Any (all)

Description:
While setting up replication, if one forgets to GRANT REPLICATION SLAVE to the replication user, then does START SLAVE,
he gets this in the error log :
> 4:36:30  Error updating slave list: Query error
Which is not very clear.

How to repeat:
do
GRANT USAGE on *.* to the_replication_user
on the master
and forget to grant REPLICATION SLAVE.
Then 
START SLAVE

Suggested fix:
I have a patch that prints something like :

The replication user used by the slave failed updating the slaves' list on the master ; while doing SHOW SLAVE HOSTS on the master he got this error:
"Access denied. You need the REPLICATION SLAVE privilege for this operation"

I will send it in a big patch for #52,#53,#70,#79 together.
