[HttpKernel] exception listener, allow easier overloading of the default behavior

Hi Fabien,

This commit you wrote about a month ago helped me to overload the 'logException' method:
https://github.com/symfony/symfony/commit/1a6c9b31438e45180001957bb64f97d1cf54ca4f

Because the logger property was private I could not access it from the subclass. This PR changes both properties: controller and logger from private to public members. So they can be used from 'logException'.
added Universal* classes in the list of deprecated classes for 3.0
[Doctrine] removed usage of the deprecated LoggerInterface in some tests
updated required versions when depending on the Yaml component

The API has not changed since 2.0 and won't until 3.0.
use ~2.0 when depending on the locale component

Some methods have been added in 2.1 but none of them are used by the
Symfony components.
use ~2.0 when depending on the CSS selector component

The API is stable and won't change.
