Bug#36443 Server crashes when executing insert when insert trigger on table
The crash appeared to be a result of allocating an instance of Discrete_interval
automatically that that was referred in out-of-declaration scope.
Fixed with correcting backing up and restoring scheme of
auto_inc_intervals_forced, introduced by bug#33029, by means of shallow copying;
added simulation code that forces executing those fixes of the former bug that
targeted at master-and-slave having incompatible bug#33029-prone versions.
mysql-test/suite/bugs/r/rpl_bug33029.result:
new results file
mysql-test/suite/bugs/t/rpl_bug33029.test:
test merely checks no crash happens on slave.
sql/slave.cc:
forcing to execute special logics implemented for bug#33029 if
simulate_bug33029 the debug option is set.
sql/sql_class.cc:
swaps of backed and the actual auto_inc_intervals_forced basing on shallow coping.
sql/structs.h:
Removing the deep _copy() and methods associated with it;
adding methods to Discrete_intervals_list:
private `=', copy constructor to prevent using;
private set_members();
public copy_shallow(), swap(), get_{head, tail, current}();
empty_no_free() through set_members().
