There was a failure in that show slave status displayed a wrong message
when slave stopped at processing a row event inserting to a default-less
column.

The problem seem to have ceased after recent fixes in rbr code.
However, the test was not updated to carry testing of the case commented-out.

Uncommenting and editing the test.
Notice, Bug#23907 is most probably a duplicate of this one.

There was no way to see if report-{host,port,user,password} were set up.

Fixed with introducing new global variables.
The variables are made read-only because of a possible need to change them
most probably require the slave server restart.

Todo: transform the startup options to be CHANGE master parameters - i.e
to deprecate `report-' options, and to change the new vars 
to be updatable at time of CHANGE master executes with new
values.

READ_ONLY token was accidentally placed into wrong place
('ident' rule). The proper place is in the 'keyword_sp' rule.

The manual should be re-generated after this patch, because
the manual depends on the 'keyword_sp' rule.

must match the order which they were declared in the class definition. 

Rename client_last_error to last_error and client_last_errno to last_errno
to not break connectors which use the internal net structure for error handling.

The problem is that passing anything other than a integer to a limit
clause in a prepared statement would fail. This limitation was introduced
to avoid replication problems (e.g: replicating the statement with a
string argument would cause a parse failure in the slave).

The solution is to convert arguments to the limit clause to a integer
value and use this converted value when persisting the query to the log.

sporadically.

(show_check.test fails sporadically).

Fix test case for Bug#12183 to make it stable.
