      Fixed memory loss detected on P8. This can happen when we call after_flush but never call after_rollback() or after_commit().
      
      The old code used pthread_setspecific() to store temporary data used by the thread.
      This is not safe when used with thread pool, as the thread may change for the transaction.
      
      The fix is to save the data in THD, which is guaranteed to be properly freed.
      I also fixed the code so that we don't do a malloc() for every transaction.

      Fixed warnings and errors found by buildbot · 71153414

      field.cc
      - Fixed warning about overlapping memory copy (backport from 10.0)
      
      Item_subselect.cc
      - Fixed core dump in main.view
      - Problem was that thd->lex->current_select->master_unit()->item was not set, which caused crash in maxr_as_dependent
      
      sql/mysqld.cc
      - Got error on shutdown as we where freeing mutex before all THD objects was freed
        (~THD uses some mutex). Fixed by during shutdown freeing THD inside mutex.
      
      sql/log.cc
      - log_space_lock and LOCK_log where locked in inconsistenly. Fixed by not having a log_space_lock around purge_logs.
      
      sql/slave.cc
      - Remove unnecessary log_space_lock
      - Move cond_broadcast inside lock to ensure we don't miss the signal

      MDEV-8474: InnoDB sets per-connection data unsafely · 7a967021
      Jan Lindström authored
      Analysis: At check_trx_exists function InnoDB allocates
      a new trx if no trx is found from thd but this newly
      allocated trx is not registered to thd. This is unsafe,
      because nothing prevents InnoDB plugin from being uninstalled
      while there's active transaction. This can cause crashes, hang
      and any other odd behavior. It may also corrupt stack, as
      functions pointers are not available after dlclose.
      
      Fix: The fix is to use thd_set_ha_data() when
      manipulating per-connection handler data. It does appropriate
      plugin locking.

      MDEV-8432 Slave cannot replicate signed integer-type values with high bit set to 1 · 00d3b20f
      Monty authored
      The fix is that if the slave has a different integer size than
      the master, then they will assume the master has the same signed/unsigned modifier
      as the slave.
      
      This means that one can safely change a coon the slave an int to a bigint
      or an unsigned int to an unsigned int.  Changing an unsigned int to an
      signed bigint will cause replication failures when the high bit of the
      unsigned int is set.
      
      We can't give an error if the signess is different on the master and slave
      as the binary log doesn't contain the signess of the column on the master.
