- Added 3 firebird specific attributes to firebird_handle_set_attribute()

- function. They control formatting of date/timestamp columns.
- pdo_firebird_handle_factory() now throwing an execption if unable to attach
- database (bug reports 39822 and 41522)
- Fixed bug #39822 (new PDO() doesn't work with firebird)
- Fixed bug #41522 (PDO firebird driver returns null if it fails to connect)
