This makes it easier for third party adapters to run our tests,
even if that database does not support IF EXISTS.

The various databases don't actually need significantly different
handling for this behavior, and they can achieve it without knowing
about the type of the object.
The old implementation was returning a string, which will cause problems
such as breaking TZ aware attributes, and making it impossible for the
adapters to supply their logic for time objects.

it doesn't work on SQLite3 since it doesn't support truncate, but that's
OK. If you call truncate on the connection, you're now bound to that
database (same as if you use hstore or any other db specific feature).

Sets the connection collation to the database collation configured
in database.yml. Otherwise, `SET NAMES utf8mb4` will use the default
collation for that charset (utf8mb4_general_ci) when you may have chosen
a different collation, like utf8mb4_unicode_ci.
This only applies to literal string comparisons, not column values, so
it is unlikely to affect you.

For mysql2/mysql adapters, `sql_mode` variable name set in `database.yml`
as string, was ignored and `sql_mode` was set to use strict mode.
Fixes #14895

When run with only the Mysql adapter, we get this failure: https://travis-ci.org/rails/rails/jobs/15937907#L2416
Porting the test over to only run when mysql2 is loaded

From PR, @tenderlove would prefer to not maintain these tests.

The MySQL connection adapater swallows all StandardError exceptions,
which includes Mysql::Error and Mysql2::Error. The comment in the
exception clause claims errors thrown here indicate that transactions
aren't supported by the server but that isn't necessarily true. It's
possible the MySQL server has gone away and swallowing a failed commit
may let the application return a successful response when the data has
not been saved. Also, replication libraries like Galera require that the
application handle exceptions thrown at BEGIN/COMMIT.
I'm unable to determine what version of MySQL threw an exception for
transactional statements. I tried as far back as 3.23.49 with InnoDB
disabled but BEGIN & COMMIT statements do not throw an error. If there's
a real case for this logic to continue, we could instead push this
behavior into a configuration setting.
The exception swallowing has been there since the beginning:

As of ccc6910c we use `mysqldump` to create the `structure.sql`.
The old `#structure_dump` code is still in AR but never used.
I removed all relevant parts from the code-base.

in the new 'variables:' hash in each database config section in database.yml.
The key-value pairs of this hash will be sent in a 'SET key = value, ...'
query on new database connections.
The configure_connection methods from mysql and mysql2 into are
consolidated into the abstract_mysql base class.

In the end I think the pain of implementing this seamlessly was not
worth the gain provided.
The intention was that it would allow plain ruby objects that might not
live in your main application to be subclassed and have persistence
mixed in. But I've decided that the benefit of doing that is not worth
the amount of complexity that the implementation introduced.

Reason since MySQL 5.6.6-m9 the `sql_mode` default value is
`NO_ENGINE_SUBSTITUTION`.
This default parameter change is out of control from Rails.
This test verifies Rails not overriding the default `@@GLOBAL.sql_mode` value
by checking if `@@GLOBAL.sql_mode` is the same as `@@SESSION.sql_mode`.

RUNNING_UNIT_TESTS file for details, but essentially you can now configure things in test/config.yml. You can also run tests directly via the command line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection from test/config.yml). This will help us fix the CI by enabling us to isolate the different Rails versions to different databases.
