When compiling GROUP BY Item_ref instances are dereferenced in
setup_copy_fields(), i.e. replaced with the corresponding Item_field
(if they point to one) or Item_copy_string for the other cases.
Since the Item_ref (in the Item_field case) is no longer used the information
about the aliases stored in it is lost.

The problem was that any VIEW columns had always implicit derivation.
Fix: derivation is now copied from the original expression
given in VIEW definition.
For example:
- a VIEW column which comes from a string constant
in CREATE VIEW definition have now coercible derivation.
- a VIEW column having COLLATE clause
in CREATE VIEW definition have now explicit derivation.

This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Allocation of memory for the sort buffer at each evaluation of a
subquery may take a significant amount of time if the buffer is rather big.
With the fix we allocate the buffer at the first evaluation of the
subquery and reuse it at each subsequent evaluation.

Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys
buffpek buffers.
sql/sql_base.cc:
Fixed bug #21727.
Made sure that st_table::pos_in_table_list would be always initialized.
sql/sql_select.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys
buffpek buffers.
sql/sql_show.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys

Cleanup.
sql/table.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added st_table_list::in_subselect() returning for a table the subselect that
contains the FROM list this table is taken from (if there is any).
sql/table.h:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added fields for sort_keys and buffpek buffers to the FILESORT_INFO structure.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Allocation of memory for the sort buffer at each evaluation of a
subquery may take a significant amount of time if the buffer is rather big.
With the fix we allocate the buffer at the first evaluation of the
subquery and reuse it at each subsequent evaluation.
Evaluate "NULL IN (SELECT ...)" in a special way: Disable pushed-down
conditions and their "consequences":
= Do full table scans instead of unique_[index_subquery] lookups.
= Change appropriate "ref_or_null" accesses to full table scans in
subquery's joins.
Also cache value of NULL IN (SELECT ...) if the SELECT is not correlated
wrt any upper select.
mysql-test/r/subselect.result:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Updated test results
sql/item.h:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Added comments
sql/item_cmpfunc.cc:
BUG#8804: wrong results for NULL IN (SELECT ...):
Made Item_in_optimizer to:
- cache the value of "NULL IN (uncorrelated select)"
- Turn off pushed-down predicates when evaluating "NULL IN (SELECT ...)"
sql/item_cmpfunc.h:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Made Item_in_optimizer cache the value of "NULL IN (uncorrelated select)"
- Added comments
sql/item_subselect.cc:
BUG#8804: wrong results for NULL IN (SELECT ...):
- When needed, wrap the predicates we push into subquery into an
Item_func_trig_cond so we're able to turn them off when evaluating
NULL IN (SELECT ...).
- Added code to evaluate NULL IN (SELECT ...) in a special way:
= In [unique_]index_subquery, do full table scan to see if there
are any rows.
= For other subqueries, change ref[_or_null] to ALL if the
ref[_or_null] was created from pushed-down predicate.
sql/item_subselect.h:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Added Item_subselect::is_correlated
- Added comments
sql/records.cc:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Make rr_sequential() non-static
sql/sql_lex.cc:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Added st_select_lex::is_correlated and Item_subselect::is_correlated.
sql/sql_lex.h:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Added st_select_lex::is_correlated
sql/sql_select.cc:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Added KEY_FIELD::outer_ref to keep track of which ref accesses are
created from predicates that were pushed down into the subquery.
sql/sql_select.h:
BUG#8804: wrong results for NULL IN (SELECT ...):
- Added KEYUSE::outer_ref
