This addresses the potential issue where a user doesn't realize that there are multiple exception messages because the
full stack trace of the first exception is displayed (pushing the others far far down the page). This hides the stacktrace
of all exceptions (when there are more than one) by default, making each exception message easily viewable.
This improves, for example, the exception one would receive if they tried to import a resource from a bundle that doesn't exist.
Previously, the deep "bundle is not activated" exception would be thrown. That has value, however there is no indication of where
the exception is actually occurring.
In this new implementation, we throw an exception that explains exactly which resource, and from which source resource, cannot be
loaded. The deeper exception is still thrown as a nested exception.
Two caveats:
* The `HttpKernel::varToString` method was replicated
* This introduces a new `Exception` class, which allows us to prevent lot's of exceptions from nesting into each other in the case
that some deeply imported resource cannot be imported (each upstream import that fails doesn't add its own exception).

[HttpKernel] removed unused class
[FrameworkBundle] fixed bugs

* kadeer/master:
[DoctrineBundle] fixes issues with $this->container->get('form.context') when the value of default_connection key of doctrine.dbal is changed from default in config.yml
The parameter has been removed and the service moved to the XML file (for consistency).
The behavior is still the same as before as any non-public service
which is not referenced anywhere will be automatically removed by a
compiler pass.
