Deprecated Driver::getName()

The method is not used for anything else than skipping tests for specific drivers. Cross-driver portability should be established by drivers, not outside of them based on their name.

Removed 2.8 from README

Removed the rest of mock classes

The usage of user-provided PDO instance is deprecated

Default column expressions do not work on SQL Server

Removed the assertion which doesn't work with a user-provided PDO connection

Reworked driver exception tests

1. Got rid of hard-coded exception mocks in favor of PHPUnit-generated ones where possible.
2. Reworked AbstractDriverTest::testConvertsException() to use a data provider to make testing all types of exceptions independent.
3. Updated PHPUnit since the reworked code relies on sebastianbergmann/phpunit#3604.

Deprecate the public constants in SQLParserUtils

Deprecate SQLSrvStatement::LAST_INSERT_ID_SQL constant.

Improve ExceptionTest::testConnectionExceptionSqLite

Reworked SQL Server installer on Travis CI
