For queries with GROUP BY and without hidden GROUP BY fields DISTINCT is
optimized away becuase such queries produce result set without duplicates.
But ROLLUP can add rows which may be same to some rows and this fact was
ignored.

Added check so if ROLLUP is present DISTINCT can't be optimized away.

This bug occurs when some trigger for table used by DML statement is created
or changed while statement was waiting in lock_tables(). In this situation
prelocking set which we have calculated becames invalid which can easily lead
to errors and even in some cases to crashes.

With proposed patch we no longer silently reopen tables in lock_tables(),
instead caller of lock_tables() becomes responsible for reopening tables and
recalculation of prelocking set.

When parser parses function convert_tz it loads available timezone tables in
thd->lex->time_zone_tables_used. But view have another lex that main query.
Thus time_zone_tables_used of main query left uninitialized.
When Item_func_conver_tz is fixed it takes timezone tables from main query
and later when it executed it assumes that timezone tables are loaded and
failed that assertion.
