Added a unit test for Doctrine\DBAL\Logging\LoggerChain

Reworked the mocks generated by Prophecy using PHPUnit

Updated PHPUnit to 8.2.1

The new version contains some improvements in handling mocks (https://github.com/sebastianbergmann/phpunit/issues/3602) and will help identify some existing issues in DBAL 3.0 tests:

There were 2 warnings:

1) Doctrine\Tests\DBAL\Driver\OCI8\OCI8StatementTest::testExecute with data set #0 (array('test', null, 'value'))
Method bindValue may not return value of type boolean

2) Doctrine\Tests\DBAL\Driver\OCI8\OCI8StatementTest::testExecute with data set #1 (array(null, 'test', 'value'))
Method bindValue may not return value of type boolean

Updated Jetbrains PhpStorm stubs to 2019.1

Deprecated some unused code bits

Make LoggerChain use constructor to add loggers instead of adder method

Enforced parameter and return value types in test classes

Upgraded to PHPUnit 8.1.6 and reworked the remaining driver exception mock

Allow Symfony 5

add .github/FUNDING.yml

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
