Bug #52629: memory leak from sys_var_thd_dbug in binlog.binlog_write_error
When re-setting (SET GLOBAL debug='') the GLOBAL debug settings the
server was not freeing the data elements from the top (initial) frame
before setting them to 0 without freeing the underlying memory. As these
are global settings there's a chance that something is there already.
Fixed by :
1. making sure the allocated data are cleaned up before re-setting them
while parsing a debug string
2. making sure the stuff allocated in the global settings is freed on
shutdown.
