"Server_IO_State" field

Critical error messages from get_master_version_and_clock() were written
only to the slave errorlog while Show slave status did not display any
incident happened.

Although the artifact was reported for a particular --replicate-same-server-id
related issue the fix refines all critical error reporting with 
deploying rli->report().

The test for the bug covers only --replicate-same-server-id error reporting.


mysql-test/suite/rpl/r/rpl_server_id1.result:
  new results reflecting changes
mysql-test/suite/rpl/t/rpl_server_id1.test:
  Preserving the idea of the test unnecessary queries and the sleep are
  eliminated.
  In the end the slave must stop with the error displayable via $$$.
sql/slave.cc:
  improving get_master_version_and_clock() code to report a critical incident
  via rli->report() that takes care of bothe the error log and
  the slave's status info placeholders.
  
  A critical error that force the IO slave thread to terminate is handled
  immediately (goto err).
