BadRequestException: Invalid URI

[ps-hidden]

Symfony added request uri validation and exception throwing in case of prohibited characters. Would like to see adequate handling of this exception or throw a more understandable exception

ref: symfony/http-foundation@168b77c#diff-de5d8eb3f1d6537c947f70e0a4673779312a902c083739f472c709c037bcbc30R366-R379

Symfony\Component\HttpFoundation\Request::create("http://foo.com\\bar");

[dbu]

sounds right to play nicely with that. which places lead to non-understandable exceptions?

i would assume at least some of the changes will go to the symfony cmf RoutingBundle, as the model and entity/document classes live there. though we have to be careful about BC, and about how the model might be created in several steps, or a workflow might even be constructed to start with an invalid model...

glad to review a pull request if you have any suggestions where we need to adjust the cmf repository for better error reporting.
