WL#5670: Proposal: Remove SHOW NEW MASTER statement

Removes SHOW NEW MASTER statement and all related code.
Also removes the unused function update_slave_list from repl_failsafe.cc.


mysql-test/r/signal_code.result:
  Updated result file.
  The output of SHOW PROCEDURE CODE has changed, because the numerical values
  of some SQLCOM_ commands have changes. This is not a problem, because
  SHOW PROCEDURE CODE only exists in debug builds and the numerical values of
  SQLCOM_ constants are not exposed elsewhere.
mysql-test/r/sp-code.result:
  Updated result file.
  The output of SHOW PROCEDURE CODE has changed, because the numerical values
  of some SQLCOM_ commands have changes. This is not a problem, because
  SHOW PROCEDURE CODE only exists in debug builds and the numerical values of
  SQLCOM_ constants are not exposed elsewhere.
sql/mysqld.cc:
  Remove SQLCOM_SHOW_NEW_MASTER.
sql/repl_failsafe.cc:
  Remove show_new_master, which was only used by the removed SHOW NEW MASTER statement.
  Remove translate_master, which was only used by show_new_master.
  Remove find_slave_event, which was only used by translate_master.
  Remove find_target_pos, which was only used by translate_master.
  Remove cmp_master_pos, which was only used by translate_master.
  Remove update_slave_list, which was not used at all.
sql/repl_failsafe.h:
  Remove declarations of functions removed by this patch:
    update_slave_list, show_new_master, translate_master, update_slave_list
  
  Remove declarations of functions that did not exist before this patch:
    handle_failsafe_rpl, load_master_data
  
  Remove declaration of function that is static in slave.cc:
    connect_to_master
sql/sp_head.cc:
  Removed SQLCOM_SHOW_NEW_MASTER
sql/sql_lex.h:
  Removed SQLCOM_SHOW_NEW_MASTER
sql/sql_parse.cc:
  Removed SQLCOM_SHOW_NEW_MASTER
sql/sql_repl.cc:
  Removed cmp_master_pos(char*,ulonglong,char*,ulonglong), which was
  only used by cmp_master_pos*Slave_log_event* sev, LEX_MASTER_INFO* mi) in repl_failsafe.cc,
  which has been removed.
sql/sql_repl.h:
  removed cmp_master_pos
sql/sql_yacc.yy:
