Upstream libs and tools have improvements that make them unnecessary.

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.

Added test case for PHP Resource as parameter in Driver exception

#2821 replacing `@group` annotations with proper references, since DBAL-* issues are from JIRA, not Github

Added upgrade notice about BC break.
Cleanups

- includes extended default driver connection parameter handling
- minor refactoring

fixes #1183

Fixed a PHP warning in DBALException::driverExceptionDuringQuery() when a parameter contains binary data.
