message:
  Bug#15192 "fatal errors" are caught by handlers in stored procedures

  The problem is that fatal errors (e.g.: out of memory) were being
  caught by stored procedure exception handlers which could cause
  the execution to not be stopped due to a continue handler.

  The solution is to not call any exception handler if the error is
  fatal and send the fatal error to the client.

mysql-test/r/sp-error.result:
  Add test case result for Bug#15192
mysql-test/t/sp-error.test:
  Add test case for Bug#15192
mysys/my_alloc.c:
  Pass flag to signal fatal error in memory root allocations.
sql/event_data_objects.cc:
  Use init_sql_alloc to initialize memory roots, which uses
  the sql error handler to push errors.
sql/ha_partition.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/item_func.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/item_subselect.cc:
  Remove redundant fatal error, memory root already pushes error.
sql/opt_sum.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/sp_head.cc:
  Allocator already sets fatal error.
sql/sql_class.h:
  A error must exist for it to be fatal. Pass flag to signal fatal
  error instead of calling fatal_error.
sql/sql_insert.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/sql_list.h:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/sql_parse.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/sql_partition.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/sql_select.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/sql_servers.cc:
  Use init_sql_alloc to initialize memory roots, which uses
  the sql error handler to push errors.
sql/sql_show.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/sql_trigger.cc:
  Use init_sql_alloc to initialize memory roots, which uses
  the sql error handler to push errors.
sql/sql_update.cc:
  Pass flag to signal fatal error instead of calling fatal_error.
sql/tztime.cc:
  Use init_sql_alloc to initialize memory roots, which uses
  the sql error handler to push errors.
