Bug #744103: Make use of InnoDB fast index creation in mysqldump, ALTER

Initial implementation of innodb_expand_fast_index_creation.patch.

This patch expands the applicability of InnoDB fast index creation to
mysqldump, ALTER TABLE and OPTIMIZE TABLE as follows:

1. mysqldump has now a new option, --innodb-optimize-keys, which changes
the way InnoDB tables are dumped so that secondary and foreign keys are
created after loading the data thus taking advantage of fast index

This part of the patch is an implementation of the feature request
reported as MySQL bug #49120.

More specifically:

- KEY, UNIQUE KEY and CONSTRAINT specifications are omitted from CREATE
TABLE corresponding to InnoDB tables.

- an additional ALTER TABLE is issued after dumping the data to create
the previously omitted keys.

Delaying foreign key creation does not introduce any additional risks as
mysqldump always prepends its output with SET FOREIGN_KEY_CHECKS=0 anyway.

2. When ALTER TABLE requires a table copy, secondary keys are now dropped
and recreated later after copying the data. The following restrictions

- only non-unique keys can be involved in this optimization

- if the table contains foreign keys, or a foreign key is being added as
a part of the current ALTER TABLE statement, the optimization is
disabled for all keys.

This part of the patch is an implementation of the feature request
reported as MySQL bug #57583.

3. As OPTIMIZE TABLE is mapped to ALTER TABLE ... ENGINE=InnoDB for
InnoDB tables, it now also benefits from fast index creation with the
same restrictions as for ALTER TABLE.
