PDO: Support for PDO::ERRMODE_EXCEPTION (PHP8)

[dakujem]

• new feature, no existing code will break (full bc)

I added support for PDO in PDO::ERRMODE_EXCEPTION error mode using a single try-catch block.

👉 Since in PHP 8 PDO::ERRMODE_EXCEPTION is the default error mode!

I think it would be best to do a BC break and add support (only) for PDO::ERRMODE_EXCEPTION in dibi 5.0 and keep version 4.2 as it is. What do you think?

Since it is backwards compatible, I see no reason not to include it in v4. It can be the default in v5.

I don't fully understand why this useful feature is still not integrated after 4 years.

Came across a note in my code that works around this shortcoming, just to see nothing has been done here nor in #393 ... now there is Dibi v5 already out which only runs on PHP 8 and that means in default settings this PDO driver will simply not work.

See here: https://www.php.net/manual/en/pdo.error-handling.php

Because of the private-access props in the driver, there is no way to just tweak the piece of code in the constructor, so one needs to copy the whole driver. 🤦‍♂️

Seems like releasing a separate package with just the improved PDO driver is the way to go.
