The patch enables back constant subquery execution during
query optimization after it was disabled during the development
of MWL#89 (cost-based choice of IN-TO-EXISTS vs MATERIALIZATION).
The main idea is that constant subqueries are allowed to be executed
during optimization if their execution is not expensive.
The approach is as follows:
- Constant subqueries are recursively optimized in the beginning of
JOIN::optimize of the outer query. This is done by the new method
JOIN::optimize_constant_subqueries(). This is done so that the cost
of executing these queries can be estimated.
- Optimization of the outer query proceeds normally. During this phase
the optimizer may request execution of non-expensive constant subqueries.
Each place where the optimizer may potentially execute an expensive
expression is guarded with the predicate Item::is_expensive().
- The implementation of Item_subselect::is_expensive has been extended
to use the number of examined rows (estimated by the optimizer) as a
way to determine whether the subquery is expensive or not.
- The new system variable "expensive_subquery_limit" controls how many
examined rows are considered to be not expensive. The default is 100.
In addition, multiple changes were needed to make this solution work
in the light of the changes made by MWL#89. These changes were needed
to fix various crashes and wrong results, and legacy bugs discovered
during development.

The fix for bug 31148 is not correct. It does not
have a relation to the problem described in this bug.
And removing the fix will not make the bug to re-appear.

Assertion `table->key_read == 0' failed.
The problem was that key_read on a table in a sub-select was not
properly reset. That happens because the code responsible for that
is copy&pasted all around the server. In some place, it was obviously
forgotten to be pasted.
The fix is to reset key_read properly.

The function that checks whether we can use keys for aggregates,
find_key_for_maxmin(), assumes that keys disabled by ALTER TABLE
... DISABLE KEYS are not in the set table->keys_in_use_for_query.
I.E., if a key is in this set, the optimizer assumes it is free to
use it.
The bug is that keys disabled with ALTER TABLE ... DISABLE KEYS still
appear in table->keys_in_use_for_query When the TABLE object has been
initialized with setup_tables(). Before setup_tables is called, however,
keys that are disabled in the aforementioned way are not included in
TABLE::keys_in_use_for_query.
The provided patch changes the code that updates keys_is_use_for_query so
that it assumes that keys_is_use_for_query already takes into account all
disabled keys, and generally all keys that should be used by the query.

Fixed confusing warning.
Quoting INSERT section of the manual:
----
Inserting NULL into a column that has been declared NOT NULL. For
multiple-row INSERT statements or INSERT INTO ... SELECT statements, the
column is set to the implicit default value for the column data type. This
is 0 for numeric types, the empty string ('') for string types, and the
"zero" value for date and time types. INSERT INTO ... SELECT statements are
handled the same way as multiple-row inserts because the server does not
examine the result set from the SELECT to see whether it returns a single
row. (For a single-row INSERT, no warning occurs when NULL is inserted into
a NOT NULL column. Instead, the statement fails with an error.)
----
This is also true for LOAD DATA INFILE. For INSERT user can specify
DEFAULT keyword as a value to set column default. There is no similiar
feature available for LOAD DATA INFILE.

The intention with the original code was to show that MySQL treats the first
given unique key as a primary key. Clients can use the marked primary key as a
real primary key to validate row changes in case of conflicting updates. The
ODBC driver (and other drivers) may also use this fact to optimize/check
updates and handle conflicts. The marked key also shows what some engines, like InnoDB or NDB,
will use as it's internal primary key.
For checking if someone has declared a true PRIMARY KEY, one should use 'SHOW CREATE TABLE'

WL#1563 - Modify MySQL to support fast CREATE/DROP INDEX
Added new flags and methods.
Removed old flags and methods (from the last attempt).
sql/share/errmsg.txt:
WL#1563 - Modify MySQL to support fast CREATE/DROP INDEX
Added a new error message for drop index.
sql/sql_table.cc:
WL#1563 - Modify MySQL to support fast CREATE/DROP INDEX
Moved definitions to the top of the file.
In mysql_prepare_table() allow an index to have the name
"PRIMARY" if it has the key type "Key::PRIMARY".
Added a parenthesis for readability.
Removed old code from the last attempt.
Some changes to compare_tables():
- Input parameter "List<Key> *key_list" is replaced by
"KEY *key_info_buffer, uint key_count".
- Output parameters added: "index_drop_buffer/index_drop_count"
and "index_add_buffer/index_add_count".
- Key comparison must now find matching keys in changed
old and new key lists.
- Key comparison of a key is easier now because both old
and new keys are of type 'KEY'.
Call mysql_prepare_table() before compare_tables(). The
translated KEY structs are needed at some places now.
Inserted a code segment for checking alter_table_flags().
Removed mysql_prepare_table() from the 'partition' branches
(it is done above now).
Removed a pair of unnecessary braces.
Inserted a code segment for executing fast add/drop index.
Made close of table dependent on whether it was opened.
Prepared for NDB cluster support.
Fixed commit to be called outside of LOCK_open.

Added assert if using QUICK_GROUP_MIN_MAX_SELECT with parent_alloc as the init() function can't handle this
Changed back get_quick_select_for_ref() to use it's own alloc root becasue this function may be called several times for one query

change variable 'err' to 'error' as same function had a label named 'err'

Removed the assumption of a certain key order.
Since 4.1, keys are padded with blanks for comparison.
Hence, shorter keys sort behind longer keys, if the
data bytes have values below BLANK.
