Class representing a lock on free_intervals_mutex.
This is used by the add_* and remove_* functions. The lock is declared by the top-level function and a pointer to the lock is passed down to low-level functions. If the low-level function decides to access the free intervals list, then it acquires the lock. The lock is then automatically released by the destructor when the top-level function returns.
The lock is not taken if Gtid_set->tsid_lock == NULL; such Gtid_sets are assumed to be thread-local.
