[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

The API has not changed since 2.0 and won't until 3.0.

Some methods have been added in 2.1 but none of them are used by the
Symfony components.

The API is stable and won't change.
