 st_table::const_key_parts member is used in determining if
 certain key has a prefix that is compared to constant(s) in
 the query predicates.
 If there's such prefix the index can be used to get the data
 from the remaining suffix columns in sorted order.
 However if a field is compared to another field from a "const"
 table the const_key_parts is not amended.
 This makes the optimizer unable to detect that the key can be 
 used for sorting and adds an extra filesort.
 Fixed by updating const_key_parts after reading in the "const"
 table.

added new field 'REFERENCED_TABLE_NAME' to 'referential_constraints' table
field 'UNIQUE_CONSTRAINT_NAME' contains the name of the referenced index

Subselect's engine checks table->status field to determine if the
record was properly found when we use keyread upon the table.
Partition engine checks all the partitions for given key
before return. So if matching record was found in the first
partition and no matching records were found in the second, 
we have table->status == NOT_FOUND after the function, what
makes subselects to skip matching records.
The patch adds table->status= 0 if we actually found something.

           aliases ignored
When a column reference to a column in JOIN USING is resolved and a new 
Item is created for this column the user defined name was lost.
This fix preserves the alias by setting the name of the new Item to the
original alias.

2nd version
During tmp tables cleanup we get the handler for temporary table
and delete table using handler method.

In the method Item_field::fix_fields we try to resolve the name of
the field against the names of the aliases that occur in the select
list. This is done by a call of the function find_item_in_list.
When this function finds several occurrences of the field name
it sends an error message to the error queue and returns 0.
Yet the code did not take into account that find_item_in_list
could return 0 and tried to dereference the returned value.

- configure --disable-grant-options defines DISABLE_GRANT_OPTIONS
- configure.js/cmake also updated
- if DISABLE_GRANT_OPTIONS is defined, mysqld no longer recognizes:
  --bootstrap
  --init-file
  --skip-grant-tables

Scripts which rely on those three options are modified to check the environment for MYSQLD_BOOTSTRAP; it should be set to the full path of a mysqld which does handle those options.

For example:

$ export MYSQLD_BOOTSTRAP
$ MYSQLD_BOOTSTRAP=/path/to/full/MySQL/bin/mysqld
$ mysql_install_db
$ make test
