Auto increment test does not need any particular columns
and should not depend, in particular, on correct handling
of binary data.
This commit moves auto increment test into its own file and
gives it its own table with a simple schema.

* bantu/ticket/10327:
[ticket/10327] Use $this->tools instead of creating a new instance of db_tools.
[ticket/10327] Also change CREATE UNIQUE INDEX to use ALTER TABLE.
* CREATE INDEX is internally mapped to an ALTER INDEX statement.
* CREATE INDEX requires the INDEX permission.
* ALTER TABLE requires the (more powerful) ALTER permission.
* We require the ALTER permission anyway for operation.
* Changing CREATE INDEX to ALTER TABLE thus removes dependency on the INDEX
permission which is good because some management software does not give
out the INDEX permission by default.

The test creates a table and runs a number of queries on it to judge whether
the selected column types can hold the data they are expected to contain.
Additional test methods check the auto increment feature and a few of the
basic commands of db_tools. This is only a starting point. Plenty more
tests need to be added.
