Alfranio Correia f9338b318e BUG#39393 slave-skip-errors does not work when using ROW based replication
RBR was not considering the option --slave-skip-errors.
                              
To fix the problem, we are reporting the ignored ERROR(s) as warnings thus avoiding 
stopping the SQL Thread. Besides, it fixes the output of "SHOW VARIABLES LIKE 
'slave_skip_errors'" which was showing nothing when the value "all" was assigned 
to --slave-skip-errors.
                  
@sql/log_event.cc
  skipped rbr errors when the option skip-slave-errors is set.
@sql/slave.cc
  fixed the output of for SHOW VARIABLES LIKE 'slave_skip_errors'"
@test-cases
  fixed the output of rpl.rpl_idempotency
  updated the test case rpl_skip_error

# BUG#19958: RBR idempotency issue for UPDATE and DELETE
# Statement-based and row-based replication have different behaviour
# when updating a row with an explicit WHERE-clause that matches
# exactly one row (or no row at all). For statement-based replication,
# the statement is idempotent since the first time it is executed, it
# will update exactly one row, and the second time it will not update
# any row at all. This was not the case for row-based replication, so
# we test under both row-based and statement-based replication both
# for tables with and without primary keys.
