FormTypeInterface::getName() is deprecated

[xabbuh]

As of Symfony 2.8, implementing the getName() method of the FormTypeInterface() is deprecated. Instead, form types should be referenced by their FQCN (which is quite easy as PHP supports the class constant since 5.5). Additionally, you should now also not use the alias attribute anymore when tagging your services as a form type using the form.type tag.

More detailed information and examples can be found in the code PR (see symfony/symfony#15079) which has just been merged.

Given that Symfony 2.8 is designed for PHP 5.3.9 and up, docs should display both the short ::class examples and the long/verbose alternatives for 5.3 and 5.4.

Indeed, that's a good hint, Javier!

Please see #5909, for the second set of huge changes for this :)

Does this mean you can't customize a form's name anymore ? I have custom prototype entry_rows for some collections that I would need to use from different forms, so I need to change the form's name.
